Photoionisation detection makes safer batteries.

Photoionisation detection (PID) sensors are able to detect potential problems before they occur in the manufacture and use of lithium-ion (Li-ion) batteries, and the enormous variety of devices that use rechargeable batteries.

The safe utilisation of Li-ion batteries is a key concern for the developers of equipment such as electric vehicles, e-bikes, mobile phones and laptops. The risks posed by Li-ion batteries have been highlighted by a number of high-profile incidents. In 2006 and 2007, for example, millions of laptops and mobile phones were recalled due to safety fears relating to their Li-ion batteries, and in 2013, a Boeing 787 was grounded following electrical issues with the Li-ion battery in the aircraft's auxiliary power unit.

Famously, in 2016, around 2.5 million mobile phones had to be recalled after complaints of overheating and exploding batteries. Extensive investigations revealed insufficient insulation material within the batteries and a design that did not provide sufficient space to safely accommodate the batteries' electrodes, resulting in thermal runaway, which occurs when temperatures are raised by thermal or mechanical failure, short circuiting, or electrical abuse. In more recent news, there has been a 60% increase in e-bike fires in London in 2023 compared to 2022, and this number will continue to rise. As a result of the magnitude of this problem, and the global publicity which ensues, demand is growing for sensing technology that can detect faulty Li-ion batteries, during both production and operation.

The main safety hazards associated with failing Li-ion batteries are the ignition of the battery cell and/or the emissions of toxic gases. These gases include volatile organic compounds (VOCs), meaning sensitive VOC sensors can be used to check the condition of these batteries – either within portable detectors or in process/plant monitoring equipment.

The anode in rechargeable Li-ion batteries is typically graphite, the cathode is a metal oxide, and the electrolyte is usually a lithium salt in a (flammable) organic solvent. This electrolyte includes compounds such as ethyl methyl carbonate (EMC) which is known to be among the gases emitted by a faulty Li-ion battery. Conveniently, EMC can be de-tected by ION Science’s PID, so the developers of monitoring systems and equipment are able to design technologies that utilise ION’s MiniPID sensors.

The Response Factors for VOCs commonly used in Li-ion battery electrolytes are presented in this Table: .

Evaluation of chemicals used in lithium-ion batteries

Due to their specificity, PID sensors are the most commonly employed technology for the detection of VOCs, and ION Science's MiniPID range includes the most sensitive PID sensor in the world, which makes it ideal for the detection of trace leaks from faulty Li-ion batteries.

Summarising, Peter Morris from ION Science says: “Prospective customers for our PID sensors in Li-ion battery applications include the developers of portable instruments, as well as the designers of monitoring systems for processes within battery manufacturing, as well as in the manufacture of EVs, e-bikes, laptops, tablets, phones and many others.”

Benzine monitor meets regulations.

A new, dramatically upgraded version of Titan, maintaining its position as the only fixed benzene-specific monitor in the world has been launched by Ion Science - Titan 2. In accordance with recent legislation changes, Titan 2 offers enhanced stability and sensitivity, supporting the company's continued mission of protecting lives and preserving the environment.

“Benzene is a toxic, carcinogenic gas representing a serious threat to many workers, as well as the environment,” explains ION Science Group Managing Director, Duncan Johns. “It is therefore vital that staff are protected by monitors that can continuously measure benzene at the low levels required by increasingly stringent international regulations. Titan 2 is the only commercially available, truly selective, fixed continuous benzene monitor worldwide that can meet this requirement.”

Titan 2 delivers unrivalled accuracy and sensitivity in benzene detection and is ideal for use in a variety of sectors, such as oil & gas, bulk storage facilities, chemical manufacturing and processing, and asphalt production.

Users of the original Titan will be familiar with the instrument’s accuracy and performance, however, within the new Titan 2 they will see core enhancements, such as a new rugged manifold, a piezoelectric micro pump for enhanced stability, a lower limit of detection, and updated PC software for easier management and control.

An occupational exposure limit (OEL) for benzene of 100 ppm was originally recommended in 1946. Following further associations with leukaemia, the OEL was reduced to 50 ppm and then to 1 ppm as the 8-hour time weighted average (TWA) exposure limit (U.S. OSHA, 1987). However, further health problems have been reported at levels below 1ppm so there is pressure in many countries to lower the limit further. For example, NIOSH recommended airborne exposure limit (REL) is 0.1 ppm (10-hr TWA) and 1 ppm during any 15-minute work period. Similarly, the current EU 8-hour TWA for benzene is 1 ppm (3.25 mg/m3). However, from 5th April 2024, the long-term exposure limit will be reduced to 0.5 ppm – and will be cut again from April 2026 to just 0.2 ppm. – Directive (EU) 2022/431 of the European parliament of the council, March 2022 (pdf).

Regulatory requirements are therefore driving the need for greater sensitivity, and these needs are met by Titan 2. Thanks to innovative technology in conjunction with industry-leading PID sensor technology, the Titan 2 has a reduced likelihood of cross-sensitivity and can detect benzene rapidly at levels as low as 0.02 parts per million (20 parts per billion). At the other end of the scale, it can detect benzene at up to 20 ppm, delivering high speed and high sensitivity.

Titan 2 captures a gas sample once every 60 seconds. The sample is then conditioned within a further 60 seconds to allow precise benzene measurement, ensuring a consistent flow of real-time data. The piezoelectric micro pump in the latest version delivers enhanced pressure and flow accuracy to ensure a rapid response and unrivalled reliability.

Titan 2 also features visible alarm capability, triggering an alert when benzene concentrations reach either of two operator-configurable levels. Twin relay outputs enable the user to integrate the unit with existing site alarm systems, while easy-to-use firmware allows a simplified calibration procedure. For analysis of readings captured by Titan 2, both 4-20mA and RS485 MODBUS communication protocols can be utilised.

A proven, robust separation method ensures specific readings for benzene, with an easy-to-read display. An internally regulated heating system ensures stable operation even at extremes of temperatures, and the new robust housing reduces contamination risk and allows for extended use in the harshest environments.

Titan 2 has been designed to comply with international safety standards, including ATEX and IECEx, making it safe for use in any environment, as well as featuring an IP65 Ingress Protection rating. ION Science’s photoionisation detection (PID) technology has been independently verified as the best-performing on the market, providing reliable, accurate solutions backed by outstanding product support. Importantly, the new, unique to Titan 2, MiniPID T2 10.0 eV Sensor features a patented design to nullify potential humidity interference, whilst ensuring a fast response, the highest levels of sensitivity and market-leading reliability.

The Titan 2 service module is designed to be backwards compatible, so in conjunction with a simple firmware upgrade now provides existing Titan customers with a quick and convenient upgrade opportunity.

Summarising, Duncan Johns says: “Benzene is one of the more dangerous VOCs so the Titan 2’s ability to reliably speciate this gas is extremely important in the protection of lives, and with lowering regulatory limits, the instrument’s enhanced sensitivity is a major advantage.”

Photo ionisation detection(PID) sensors nomination.

ION Science's MiniPID 2 sensor has been nominated in the sensor category of the 2023 Instrumentation Excellence Awards. Voting is invited at the Awards website (Voting closes 11th Aug 2023).

“We are thrilled to be nominated,” explains ION Science Group Managing Director, Duncan Johns. “Not only does this demonstrate our leading global position as a sensor manufacturer, but it also highlights our focus on research and development, as we seek to continuously improve sensor performance. I therefore hope that as many people as possible will vote for the MiniPID 2 in recognition of the outstanding work conducted by our sensor development team.”

PID (photo ionisation detection) sensors can detect hundreds of volatile organic compounds (VOCs) such as fuels, petrochemicals, solvents, paints, adhesives, cleaners etc. VOCs can be harmful to both health and the environment, so PID sensors perform a vital role in the protection of lives, facilities and the environment.

ION Science says that the award nomination for the MiniPID 2 reflects the unique levels of performance that the sensor delivers. These include: a patented design to nullify potential humidity interference; a fast response; the highest levels of sensitivity; market-leading reliability, and the widest choice of PID lamps to optimise sensors for different applications.

Gas leak detection.

The new Panther gas leak detector just launched by ION Science, features a host of new features and twice the sensitivity of its predecessor, the GasCheck G.

The first ever ‘GasCheck’ was launched in 1990, offering industrial users the ability to detect leaks of gases such as hydrogen and helium. Later, more advanced versions were developed with new features such as over-range protection and audible alarms. Today, the new Panther PRO represents a quantum leap in technology, with a highly sensitive thermal conductivity sensor that is able to rapidly detect a variety of gases – the most popular applications are helium, hydrogen, ammonia and refrigerants.

The Panther PRO allows users to zero the instrument in ambient air, providing visual, audible and vibration alarms when leaks are detected. A colour LCD display and a built-in Gas-Table enables the measurement of concentration and leak rates in a variety of user-selectable units. All measurements can be logged internally and downloaded via Bluetooth or USB. The Panther also features an integrated torch and a flexible probe, which help in low light and restricted areas.

For customers with a smaller budget, a basic Panther model is available. This instrument has the same features as the PRO version, but without the data logging and Bluetooth capabilities.

Panther and Panther PRO have been designed for demanding applications and challenging environments, with an internal rechargeable battery that lasts for up to 19 hours.

Summarising the advantages, ION Science Product Manager Peter Barratt says: “We have over thirty years of experience, supplying thousands of customers in applications such as quality control, laboratory, cleanroom, medical, manufacturing, and research, so we have a very clear understanding of the features required of a professional gas leak detection instrument. We therefore know that customers will be delighted with the modern design, specification and performance of the Panther.”

Contaminated land and the vital role of portable PIDs.

Portable photoionization detectors (PIDs) have become an important tool in the management of many contaminated land remediation projects, and the following article will explain the reasons behind their popularity, despite the challenges presented by field work. Remediation sites frequently present soil samples with high levels of humidity, which interferes with the readings from many PIDs, so this article, from ION Science, explains how PID instruments have completely eliminated this issue.

Background.
Land is defined as contaminated when it is polluted by substances that cause, or may cause, significant harm to people, property, protected species, surface waters or groundwater. Most pollution is caused by existing or historical human activities such as industrial processes and mining, poor waste management, unsustainable farming practices, accidents, spills, leaks and the effects of armed conflicts. Pollution also knows no borders, with contaminants spreading atmospherically and through terrestrial and aquatic ecosystems.

Typical contaminants include heavy metals, asbestos, radioactive substances, oils, fuels, tars, chemicals such as solvents, and a wide range of gases. Many thousands of different contaminants therefore exist, and sophisticated laboratory analytical techniques can be used to quantify sample concentrations. However, laboratory testing is costly and incurs a significant delay, so it is common practice to deploy field-use screening devices to speed up the process of contamination assessment, and to reduce the number and cost of samples requiring laboratory analysis. It is usually necessary for field testing to be supported by confirmatory sampling and laboratory analysis.

Field-use screening tools help to identify contaminated areas quickly and cost-effectively. For example, portable XRF analysers enable rapid measurement of several metals, and PID instruments can detect hundreds of volatile organic compounds (VOCs). The ION Science Tiger XT, for example, has an internal gas table for over 700 gases, with response factors for each.

Hydrocarbon contamination.
Hydrocarbon contamination is frequently encountered in site investigations at brownfield sites, where elevated concentrations of oil and petroleum hydrocarbons in soil and groundwater systems present a risk to human health and the environment. Hydrocarbon contamination is therefore one of the most common forms of pollution, which explains why portable photoionization detectors (PIDs) are the most commonly employed tool in the screening and characterisation of potentially contaminated sites.

Further Reading. Land contamination – technical guidance. (GB Gov) SEPA Land remediation and waste management guidelines. (GB Gov) UNEP Global Assessment of Soil Pollution.(UN)  Overview of Field-Based Analytical Techniques, Devices and Kits to Determine Petroleum Hydrocarbons in Soil’ (CONCAWE) USEPA. Contaminated Land: Applications in Real Environments. (CL:AIRE  library)  Petroleum hydrocarbons in groundwater.(CL:AIRE )  Petroleum Hydrocarbon Contamination in Terrestrial Ecosystems - Fate and Microbial Responses. (Truskewycz et al. (2019) National Library of Medicine)

The more significant groups of hydrocarbons that are either indicative of oil-based pollution or represent a significant human health or environmental hazard are BTEX (benzene, toluene, ethylbenzene and xylenes) and PAHs (polycyclic aromatic hydrocarbons).

Portable PIDs can be used to test the air surrounding a potentially contaminated sample, or the sample of water or soil may be contained within a tube, jar or sample bag so that the VOCs are allowed to volatilise and accumulate. The PID can then be used to test the headspace inside the sample container. This is a useful test for water samples that may have been contaminated by leaking underground storage tanks for example. VOCs such as methyl tertiary-butyl ether (MTBE) are highly soluble in water, and are therefore extremely mobile and capable of contaminating large volumes of water such as aquifers. Odour may be detected from water contaminated by hydrocarbons, but subjective assessments such as these should be verified by PID measurements. Early identification is therefore vital because remediation of underground water resources can be problematic and costly.

Why use portable PIDs?
Portable PIDs are commonly deployed at every stage of a contaminated land project. This includes preliminary risk assessments involving site visits to define project objectives, and to identify sources, pathways, receptors and pollutant linkages. Portable PIDs are also used during subsequent site investigations to undertake risk assessments using site specific data, and to refine the conceptual model.

Soil Sampling

Once onsite work is underway, the operators of machinery, such as diggers and remediation equipment, need to know whether a sample is contaminated or not. A precise analytical measurement is frequently not required for ongoing operational purposes. All that is necessary is a fast indication of whether significant levels of VOCs are present, so that the operator can make an informed decision, such as where to excavate. Similarly, a fast indication of contamination is necessary when onsite remediation is undertaken – for samples both before and after treatment.

It is important to emphasise that portable PIDs do not replace laboratory analysis; they complement such work and help to mitigate the cost, delays and labour involved with the analysis of collected samples. It is also important to note that the collection and transport of samples for VOC analysis in a laboratory involves stringent procedures to ensure that VOC levels do not dissipate before analysis. Nevertheless, analysis in a suitably accredited laboratory is necessary for a prescribed number of samples to demonstrate that a site is complying with its licence.

Portable PIDs are also employed to test the headspace of soil probes that are sometimes deployed for site characterisation and to check the ongoing effectiveness of remediation.

A variety of alternative methods, test kits and instruments exist for the onsite measurement of VOCs, but most of these are either costly, cumbersome, not portable, time-consuming, or too specific in their target species. Flame ionization detectors (FIDs) are also responsive to a wide variety of VOCs, including alkanes, but this includes methane (PIDs do not respond to methane) which is often present in soil for reasons unrelated to contamination. Also, FIDs require an ignition source such as hydrogen, which makes them less well suited to field work.

The main advantages of portable PIDs are:

• Fast response
• Sensitive to hundreds of VOCs including BTEX and PAHs
• Highly sensitive. With a broad range
• Relatively low cost
• Simple to use by untrained staff
• Battery powered and portable
• Different lamps available to target specific groups of compounds

Underlining the importance of PIDs in the measurement of hydrocarbons, CONCAWE, an environmental research group comprising many of the world’s leading oil companies, published a report in 2021 entitled ‘Overview of Field-Based Analytical Techniques, Devices and Kits to Determine Petroleum Hydrocarbons in Soil’. The report concluded: “It is important to acknowledge that there is currently not a single field analytical technology that allows to determine and quantify the entire range of petroleum hydrocarbons in soil and therefore a combination of analytical technologies (i.e., combining PID with vis-NIR or GC-MS with vis-NIR) has the potential to offer a more robust approach in quantifying petroleum hydrocarbons in soil by providing greater prediction accuracy.”

PIDs are also employed during emergency response situations that arise when land contamination occurs from a leak or spill of hydrocarbons. For example, the USEPA has an established set of emergency response procedures to investigate a site, evaluate the threat, and determine the best course of action. For example, the choice of PPE is informed by the identification of hazards or suspected hazards, the potential exposure pathways, and the performance of equipment providing a barrier to these hazards. An important goal of monitoring during initial site entry is to establish safety zones at the site. Periodic monitoring is then conducted to ensure that any new hazards are identified promptly, and that appropriate controls are implemented to protect the responders and nearby communities.

Why use ION Science PIDs?

Portable PID instruments such as the ION Science Tiger XT have been designed specifically for challenging field conditions. These rugged instruments benefit from the advanced features of the MiniPID 2 sensors, such as detection limits down to 1 ppb, and measurement ranges up to 20,000 ppm. Crucially however, the Tiger XT range is unaffected by the problems that plague other PID instruments. This is because a unique design eliminates any potential effects of varying humidity and contamination, and a built-in ASIC chip constantly checks PID performance to deliver a fail-safe instrument, which is essential in potentially hazardous applications.

In addition to the health risks posed by VOCs, their accumulation in contaminated land can represent an explosion risk, so the ION Science portable PIDS benefit from global Intrinsic Safety (IS) certification for use in potentially explosive atmospheres.

The Tiger XT is supplied as standard with a 10.6 eV lamp for the measurement of a wide range of VOCs. However, benzene is a particularly toxic VOC, and some site conditions set specific targets for this compound. Importantly, the new Tiger XT Select (XTS) utilises the ION Science 10.0 eV lamp to detect Total Aromatic Compounds (TACs) such as benzene, toluene and xylene, and is supplied with a pack of pre-filter tubes for the specific, selective detection of benzene. This speciation capability for benzene is a major advantage, given the complexity and cost of alternative benzene-specific measurement techniques.

Eliminating humidity interference.
For decades, the users of portable PID instruments have endured unreliable measurements from their instruments due to the high levels of humidity that often exist on-site and in the headspace of soil samples. This has been the source of enormous frustration, but the wide-ranging response and the sensitivity of PIDs has made them an important tool in site investigation and sample screening work.

A number of ‘work around solutions’ have been developed involving humidity suppression or compensation, but all of these have significant limitations:

• Humidity sensor – these typically have a slower response than the PID sensor itself which causes a drifting compensation
• Desiccant tube – these both slow and reduce the PID response, plus they need replacing from time to time which adds cost
• Humidify the calibration gas – this only works at one level of humidity and is no longer accurate when the humidity changes

Importantly, none of these ‘solutions’ solves false positive readings at high humidity levels. ION Science has therefore developed a patent protected solution to high humidity, involving the addition of a third fence electrode within the PID sensor. This overcomes the possibility of incorrect high readings by acting as a conductive break, and thereby preventing excessive current flow caused by the presence of high, and even condensing, levels of humidity.

Summary.
In the many locations with hydrocarbon contamination, portable PIDs offer environmental consultants, engineering contractors, regulators and remediation companies the opportunity to quickly assess large numbers of samples and locations. These measurements are not used to demonstrate compliance with licence conditions, but they are essential for operational purposes; enabling rapid, low-cost risk assessments and enabling effective, informed, decision making during the remediation process. 

"In the Tiger XT, users have a device that is truly fit for purpose; rugged, portable and sensitive to an enormous range of VOCs, but also resistant to the contamination and humidity issues that affect other manufacturers."

Investigations into fires & explosions.

Danati Fire and Safety is a leading investigator of fires and explosions covering Southern Africa. Their first professional fire investigation was performed in 2003, and they perform an average of 250 investigations a year covering vehicles, structures and shipping vessels. 

The growth of Danati Fire and Safety can be attributed to verbal recommendations between insurance companies and loss adjusters in South Africa. A small number of private individuals may contact Danati Fire and Safety for private investigations either to counter a negative insurance claim or to simply satisfy their own curiosity.

After firefighters extinguish a fire, an investigation is launched to determine the origin and cause of the incident. Investigations are carried out using a systematic approach combined with knowledge of basic fire science. For a fire to occur, there must be fuel, oxygen and an ignition source, which must be in the specific proportions. There is a very definite science to investigating fires, and experience really counts here. The fire scene must be carefully evaluated and documented to locate the source of the fuel and possible ignition sources. Potential causes will be ruled in or out depending on the evidence presented by the fire scene, burn patterns, and physical remains. Frequently, samples are taken and sent away for evaluation, which can be a lengthy and costly process.

Danati was first introduced to the ION Science Tiger by Impact Instruments and chose the Tiger over other similar products due to its lower cost, portability and technological superiority, as well as the excellent customer service provided by thr team at Impact Instruments.

Danati’s Lead Fire Investigator, Danny Joubert, has said, “The instrument is extremely sensitive and will almost always give some level of reading when it is exposed to fire debris. Having done so on numerous occasions, I can honestly say that there are many positive aspects to the Tiger VOC detector.
“It must be understood that this instrument does not provide a definitive test for the presence of a specific accelerant or ignitable fluid. What it does do is indicate where higher than usual concentrations of VOCs may be present, and this will then prompt the investigator to take appropriate samples for laboratory testing, as per the NFPA 921 guidelines. Without the VOC detector, the average investigator can only rely on an interpretation of burn patterns and their sense of smell to detect the possible presence of a VOC.
“The Tiger adds a new dimension, and has allowed a far more thorough screening of debris to take place whilst the investigator is moving through the scene.
“The unit is very sensitive, allowing the investigators to disregard debris that might otherwise have been collected and subjected to expensive laboratory testing. Certified for use in explosive atmospheres, with high levels of sensitivity and resistance to interference from humidity or contamination, the Tiger is the only handheld instrument of its kind in South Africa, so it has allowed Danati bragging rights, which is always a morale booster!”

The biggest success of the Tiger for Danati related to a supermarket fire that was initially believed to be caused by an electrical surge following a period where the electricity was shut down.

The instrument was started up, and the investigator entered the building. The Tiger immediately gave a reading, turning left, the readings dropped, and walking further into the premises caused the instrument to give an alarm. This was the first audible alarm that the instrument had given, and the readings were extremely high. Standard human olfactory sensing could not detect anything above the normal stench of a three-day-old fire scene in a supermarket. Using the Tiger, the source of the alarm was found, and samples were taken. The samples were sent to a laboratory, and the intentional nature of the fire was put beyond any question.

The instrument shortened the investigation time considerably, and it was also noted that two other investigation firms were in attendance; their reaction to the Tiger was a combination of awe and jealousy.

Detecting deadly hydrogen sulphide.

Hydrogen Sulphide (H₂S) is a fast-acting poison that can desensitize and render the body unconscious in no time. As the human senses are not reliable indicators, wearable gas sensors are necessary for early detection. ION Science’s new ARA H₂S personal single gas monitor offers 24 months’ continuous operation and robust design for use in harsh environments. It enables workers in a wide range of industrial process applications to monitor their exposure to the toxic gas and provide an alert when safe levels are exceeded.

H₂S is commonly found during the drilling and production of crude oil and natural gas, plus in wastewater treatment and utility facilities and sewers. The gas is produced as a result of the microbial breakdown of organic materials in the absence of oxygen and can also be found in textile manufacturing, food processing, hot asphalt paving and mining.

Colourless, flammable, poisonous and corrosive, H₂S gas is noticeable by its rotten egg smell but continuous exposure to even low levels quickly deadens olfactory desensitisation. Although the scent of H₂S is a characteristic, smell is not a dependable indicator of gas presence or for indicating increasing concentrations of it.

With toxicity similar to carbon monoxide which prevents cellular respiration, monitoring and early detection of H₂S could mean the difference between life and death.

The small, lightweight ARA H₂S single gas detector is low maintenance, disposable and offers a continuous run time of two years as standard, whilst an additional hibernation model provides three years’ operation. The instrument help employees work safely and cost-efficiently, providing an alert to the presence of unsafe H₂S levels.

The ARA H₂S single gas detector is designed for use as a safety compliance device to be worn throughout daily shifts within a range of industry sectors including oil & gas, chemical, manufacturing, government & defence, water, aerospace and power generation, and across a variety of applications such as site-wide safety, confined space entry, plant shutdown processes and first response safety.

User set low and high alarms will alert the wearer and surrounding colleagues to the presence of hazardous H₂S gas exposure. When an alarm occurs, the user must exit the area or put-on PPE, in line with company or local health and safety guidelines.

This low-maintenance single gas detector is easy to use and operate with one button operation. The user simply switches the instrument on, and it will operate continuously for two years displaying real-time readings and instantaneous alarms to protect the workforce within hazardous environments.* Hibernation models allow the device to be placed on standby to extend battery life up to three years**.

An additional benefit of the ARA H₂S single gas detector is its lifetime remaining countdown feature that helps users to plan for future projects and site shutdowns.

ARA’s self-test feature tests the audio, visual & vibrating alarms, giving users confidence that they are in safe hands. Easy to perform in a single button press and with user-configurable reminders, the self-test reassures users that their device is in safe working condition. 

The ARA H₂S single gas detectors can be connected to PC software via the ARA IR link, to set bump test and calibration reminders as well as low / high user adjustable alarms. The ARA PC allows users to download 30 recent event logs and configure user settings.

* ION Science recommends that devices are bump tested prior to each use. 
** Based on daily 1 minute alarm.

Long life disc pumps.

As part of its exclusive agreement with TTP Ventus to distribute the award-winning Disc Pump,  ION Science has introduced the long-life LT Series. These latest pumps offer in excess of 5,000 hours continuous operation under the most demanding conditions, with the potential to run up to 10,000 hours for other applications.

The LT Series is designed for applications with demanding operational life requirements. An excellent fit with ION Science’s photoionisation detection (PID) sensors, the new LT-S2-023 and LT-P2-024 models have higher power ratings than other models and deliver high performance without compromising on service life.

All Disc Pumps offer key features for  gas detection, monitoring, analysis and sampling industries including silent, vibration-free operation, true pulsation-free flow, fast response to set-point changes, high precision controllability and resistant to magnetic fields. 

These benefit many applications by allowing, simpler instrument design – especially for chromatographic systems, lower limits of detection, real time capability to respond to trigger conditions, intermittent sampling against pressurised lines, and improved user experience in wearable applications. 

Tom Harrison, Business Development Manager at TTP Ventus comments: “Over the first twelve months of our partnership, Ion Science has helped TTP Ventus to establish our presence the global gas detection industry. We’re now delighted to expand the range of pumps we offer to include the new LT Series. These long-life models take advantage of innovative design improvements that allow our pumps to be driven harder, for longer. The resulting performance boost broadens the number of applications that can take advantage of the core benefits of the Disc Pump platform, including fixed systems with long service intervals.”

Most piezoelectric gas pumps rely on the movement of a piezo actuator to compress the gas in a cavity which increases its pressure. Such ‘displacement’ pumps have limited performance because the movement of piezo actuators is very small. 

In contrast, Disc Pump’s piezo oscillates at ultrasonic frequencies to create an internal standing wave which enables much greater pressure and flow than traditional piezo pumps.

Turning an ultrasonic standing wave into useful pumped flow requires a highly specialised valve, able to respond in a matter of microseconds. The patent-protected Disc PumpTM achieves this delivering unrivalled pneumatic performance.  Disc PumpTM is already widely used in the gas and leak detection markets and the arrival of the LT series will open more applications.

Monitoring hazardous agents.

In line with China’s new occupational exposure limits for Chemical Hazardous Agents in the Workplace which took effect on 1 April 2020, Purolite Corporation China is using a Mercury Vapour Indicator (MVI) from Ion Science to help ensure the health and safety of its employees. The handheld instrument is measuring mercury vapour levels in an area used for mercury intrusion porosimetry to calculate the porosity of speciality ion exchange resin.

Purolite is a leading manufacturer of quality ion exchange, catalyst, adsorbent and speciality high-performance resins for complex regulatory environments including biotechnology, pharmaceutical, food, fine chemical and electric power generation. The company focuses 100% of its resources on the development and production of resin technology.

Xihua Yu, Purolite’s Lab Instruction Engineer comments: “As part of our quality control process, we conduct mercury intrusion porosimetry to measure the porosity of our resin. This is because the porosity of a material not only affects its physical behaviour but also its durability and decay rate.

“In line with the requirements of the newly updated ‘occupational exposure limit of hazardous agents in the workplace’ GBZ 2.1-2109 regulations, it is important we monitor the mercury vapour concentration in the area where the porosimeter instrument is located to ensure the health and safety of our staff.”

In accordance with the Chinese regulations, short term exposure limit of hazardous agents in the workplace is mercury vapour: 0.040mg/m3.

“We chose the Ion Science MVI over competitor instruments due to its simple, lightweight design and ability to detect mercury within three seconds, as well as the after sales service and technical support,” Xihua Yu adds.

Mercury intrusion porosimetry (MIP) is a technique used for the evaluation of porosity, pore size distribution, and pore volume (among others) to characterise a wide variety of solid and powder materials. The porosimeter employs a pressurised chamber to force mercury to intrude into the voids in a porous substrate. As pressure is applied, mercury fills the larger pores first. As pressure increases, the filling proceeds to smaller and smaller pores.

Ion Science’s MVI is a revolutionary handheld instrument that can detect mercury in just three seconds. Ergonomically designed for simple, one-handed operation, it is the ideal survey unit for rapid and reliable mercury detection. It helps to pinpoint mercury sources in even the most challenging environments.

The MVI’s dual beam UV technology eliminates the problem of saturation and the need for regeneration between readings, maximising its availability and uptime. A high-performance pump ensures fast indication and recovery and the instrument’s audible alarm and large digital display clearly indicate the levels of mercury present.

Fast and accurate, the MVI provides continuous readings and offers two detection ranges of 0 – 200 µg/m3 (res. 0.1 µg/m3) and 0 – 2000 µg/m3 (res. 1 µg/m3). These two ranges provide critical coverage for the OSHA PEL at 100 ug / m³ and the IDLH at 1000 ug / m³.

Xihua Yu concludes: “The Ion Science MVI operates very well and provides fast, accurate results. Based on our experience so far, I would be pleased to recommend it to other manufacturing businesses.”

Robotics aid safety in oil & gas.

Throughout unmanned facilities within the oil and gas industry, a human presence is generally still needed for regular inspection work, so deploying Ex certified robots (ATEX and IECEx Zone 1) incorporated with the ION Science Falco, can have a significant positive impact on safety by minimising worker field trips, which in turn reduces operating costs.

ION Science’s Falco VOC (volatile organic compound) monitor boasts fast response times and several innovative design features. The instrument’s typhoon technology prevents condensation forming on the sensor making it ideal for use in high humidity and harsh weather conditions.

Ian Peerless, Operations Director at ExRobotics comments: “Our robots are used in the oil and gas industry mainly for first response, fugitive emission and preventative maintenance. The introduction of more stringent fugitive emission regulations and the subsequent opening up of new markets prompted the need for a fixed gas detection instrument that could be incorporated into our remotely operated ExR-1 robot.

“The ION Science Falco VOC monitor was recommended by a significant player in the oil industry who conducted extensive performance tests and trials at a large refinery where the Falco came out on top. When ExRobotics did testing of its own, we also found the detector to be robust and reliable.”

The ExRobotics ExR-1 robot is equipped with camera’s for visual inspection, microphones for sound monitoring and the Falco gas detector for leak detection. It sends an alarm to the control room if a leak is detected.

ExR-1 with Falco navigates autonomously through installations and find its way back to its docking station to recharge. This means that inspectors and operators can reduce their visits to remote or hazardous locations, greatly improving their work safety.

Sulphur hexafluoride leak detector.

New cost effective, easy to use SF6 (sulphur hexafluoride) leak detector offers selectable sensitivity and automatic zero

ION Science has launched the portable SF6 (sulphur hexafluoride) LEAKMATE leak detector. The cost effective, easy to use instrument offers selectable sensitivity and automatic zero.


With a detection threshold of 1 x 10E-6 mbar I/s, SF6  LEAKMATE is ideally suited for simple leak detection applications on SF6  switchgear, service and maintenance in SF6 switchgear production and mobile leak detection on test equipment for differential pressure, mass flow, etc.

The processor controlled instrument features both an audible alarm and an LED bar graph display, allowing estimation if a small, medium or big leak is being detected.

It automatically compensates all ambient influences like temperature changes or movement of air in the room. Intelligent control sets up the instrument appropriately for the ambient situation.

It then uses the present gas concentration as its zero line and begins to look for even higher gas concentrations, which occur when a leak is approached. This will again be indicated audibly and visually. It is possible to determine leaks even in seriously contaminated areas.

SF6  is widely used in the electrical industry to prevent short circuits and accidents. Leaks of the colourless, odourless and synthetic gas in Britain and the European Unity (EU) in 2017 were the equivalent of putting an extra 1.3 million cars on the road.

It is a hugely effective insulating material for medium and high voltage electrical installations. It prevents electrical accidents and fires and typical applications include large power stations, wind turbines and electrical substations in towns and cities.

Although SF6  is a non-toxic gas, it can displace oxygen in the lungs and cause asphyxia if too much is inhaled. It is approximately five times heavier than air and, if released or leaked in large enough quantity, will accumulate in low lying areas where there is no natural ventilation.

For utility employees, this type of exposure is well within the normal course of duties when working on SF6  filled switchgear in enclosed spaces. Indeed, if a substantial quantity of SF6 gas leaks in an enclosed area, it can pose a real danger of asphyxiation to personnel.

Fighting arson.

Handheld, portable photoionisation detectors help emergency services, fire and rescue to detect volatile organic compounds from ignitable liquids

In the on-going fight against arson-related incidents, Merseyside Fire & Rescue Service (GB) is using TigerLT photoionisation detectors (PIDs) from Ion Science to detect volatile organic compounds (VOCs) from ignitable liquids that have been used in the development of a fire.

Supplied by Ion Science’s local distributor, Shawcity, the handheld, portable TigerLT PID instruments have helped reduce costs and increase quality by preventing non-contaminated samples being sent for lab analysis.

A long-standing user of Ion Science PID instruments for more than 10 years, Merseyside Fire & Rescue Service originally used the company’s PID FirstCheck 1000+. When these became obsolete, they purchased two Tiger PIDs and have recently added two TigerLT units to their growing portfolio of Ion Science VOC monitors.

Merseyside Fire & Rescue Service’s team of four fire investigators are each issued with a personal Ion Science Tiger or TigerLT for fire investigation purposes.

Over a five-year period, Merseyside Fire & Rescue Service attended more than 1,500 incidents where fires were deliberately set using ignitable liquids. This is an average of six incidents every week.

Ian Mullen, Station Manager at Merseyside Fire & Rescue Service, Incident Investigation, comments: “Ion Science Tiger PIDs are a robust and reliable product for detecting VOCs during fire investigations.

“The instruments are a tool to assist in the detection of the presence of ignitable liquids. This also allows the Police CSI to take a sample from a ‘confirmed’ area of post-fire ignitable liquids which can be sent for lab analysis.

“This prevents non-contaminated samples being processed which reduces costs and increases the quality of positive hits for ignitable liquids.

“The Tiger PIDs perform well. Our fire investigators take an instrument to each and every one of the 300 plus incidents they attend each year,” he adds. “The unit will be deployed if ignitable liquids are suspected to have been a factor in the incident.”

The TigerLT offers worldwide Intrinsic Safety (IS) certification for use in potentially explosive atmospheres. It is a streamlined, low cost version of the well proven Tiger PID model.

Like all Ion Science PID instruments, the TigerLT incorporates the company’s advanced patented fence electrode technology. This unique triple- electrode technology ensures increased resistance to humidity and contamination for ultimate reliability and accuracy in the field.

With a detection range of 0 - 5,000 ppm, with a 0.1 ppm minimum sensitivity, Ion Science’s TigerLT also offers an unrivalled industry response time of just two seconds and equally quick clear down.

Both simple to operate and service, the TigerLT offers easy access to the lamp and sensor. The intrinsically safe instrument also meets ATEX, IECEx, UL and CSA standards.

It features long life rechargeable Li-ion batteries that can be safely replaced in hazardous environments and give up to 24 hours usage. Fast battery charging allows the instrument to be fully charged in 6.5 hours, while eight hours of use can be achieved from 1.5 hours of charging time.

TigerLT features a protective, removable boot for harsh environments, while a large, clear back-lit display allows for easy viewing in any light condition. It is IP65 rated against water ingress. An integrated torch helps direct the instrument’s probe into dimly lit areas. Other features include a loud 95 dB audible alarm, multiple language support and is IP65 rated against water ingress.

Ian comments: “The service from Ion Science and its distributor Shawcity has always been very good. We can’t fault the Tiger PIDs which offer a number of practical features for fire investigation, a short power up time, rubber boot, bright colour for ease of visibility and robust design.”

Mercury contamination monitoring.

The ergonomically designed Mercury Vapour Indicator (MVI) from Ion Science, is suitable for rapid and reliable mercury detection during decommissioning, demolition, repurposing or refurbishment of industrial plant, laboratories and other premises.

Environmental pressures and subsequent legislation* to control hazardous substances has resulted in a sharp decline in the use of mercury although it remains an important chemical in many industrial processes, including the production of chlorine, cement, caustic soda and sulphuric acid and a wide range of products.

Exposure to excessive levels of mercury can permanently damage or fatally injure the brain and kidneys. Elemental mercury can also be absorbed through the skin and cause allergic reactions.

When properly contained and controlled, mercury can be used safely. Problems start when premises that have historically used the chemical are demolished, decommissioned, repurposed or refurbished. It means mercury that has been contained for decades can be released into the environment.

Ensuring that facilities are safe during construction and that there is no health risk associated with any repurposed land and new or refurbished buildings when they are occupied places an emphasis on effective contamination monitoring.

The  MVI is a revolutionary handheld instrument that can detect mercury in just three seconds. The MVI’s dual beam UV technology eliminates the problem of saturation and the need for regeneration between readings, maximising its availability and uptime.

Fast and accurate, Ion Science’s MVI provides continuous readings and offers two detection ranges of 0 – 200 µg/m3 (res. 0.1 µg/m3) and 0 – 2000 µg/m3 (res. 1 µg/m3). These two ranges provide critical coverage for the OSHA PEL at 100 ug / m³ and the IDLH at 1000 ug / m³.

A high-performance pump ensures fast indication and recovery and the instrument’s audible alarm and large digital display clearly indicate the levels of mercury present.

Other conventional monitoring technologies have limitations. For example, cold vapour atomic absorption is excellent at detecting sub parts per billion (ppb) concentrations of mercury but is far too sensitive for use industrial premises and will over-range, making it impossible to pinpoint mercury sources.

Gold film mercury vapour instruments offer a much wider range but are quickly saturated and then have to be regenerated away from the contaminated area before they can be used again.

Ergonomically designed for simple, one-handed operation, the MVI is the ideal survey unit for rapid and reliable mercury detection. It helps to pinpoint mercury sources in even the most challenging environments.

*The (British) Clean Air Act regulates 188 air toxics, also known as ‘hazardous air pollutants’. Mercury is listed as one of these air toxics. The Act directs EPA to establish technology-based standards for certain sources that emit these air toxics. Those sources also are required to obtain Clean Air Act operating permits and to comply with all applicable emission standards

Odour control in Guernsey.

Handheld PID instrument used on outlets of odour control system to assess utilisation of carbon media filter.

Guernsey’s States Works is using an Ion Science  handheld photoionisation detector (PID) to measure volatile organic compounds (VOCs) being emitted from an odour control system installed at Guernsey’s waste transfer station. Supplied by distributor Shawcity and chosen for its portability, high detection rates and range of response factors, the instrument is helping to prevent the escape of malodours into the surrounding environment.

States Works is using the Ion Science Tiger^LT PID instrument at three outlet ports on each of the transfer station’s odour control carbon filter vessels where it is monitoring VOCs being emitted at quarter, half and three quarters depths of the carbon filter media. It enables States Works to estimate usage of the media so they can be replaced to ensure malodours are not being released into the air.

Yannic Bearder, Senior Environmental Monitoring Technician at States Works, comments: “Part of our role is to ensure that the new waste transfer station and old landfill sites are not affecting the environment or impacting the local community.

“The company that installed the odour control system at the waste transfer station recommended we use Ion Science’s Tiger PID to measure VOCs from the three outlet ports to help assess utilisation of the carbon filter media.”

This instrument is being used by States Works for weekly monitoring of VOCs with the data downloaded manually via USB and logged onto a spreadsheet.

Tiger^LT, which offers worldwide Intrinsic Safety (IS) certification for use in potentially explosive atmospheres, is a streamlined, low cost version of Ion Science’s well proven Tiger PID model.

Like all Ion Science PID instruments, the Tiger^LT incorporates the company’s PID technology with advanced patented fence electrode system. This three-electrode format ensures increased resistance to humidity and contamination for ultimate reliability and accuracy in the field.

With a detection range of 0.1 - 5,000 ppm utilising a standard two-point calibration protocol, Ion Science’s robust TigerLT also offers an unrivalled industry response time of just two seconds and equally quick clear down.

Both simple to operate and service, the Tiger^LT offers easy access to the lamp and sensor with batteries that can be safely replaced in hazardous environments. The intrinsically safe instrument also meets ATEX, IECEx, UL and CSA standards.

Yannic continues: “Ion Science’s distributor Shawcity recommended the Ion Science Tiger^LT VOC monitor as it met our requirement for portability, high detection rates and range of response factors. Although the instrument is only being used outdoors for short periods of time, it also has a reassuringly rugged design.”

The Tiger^LT six pin MiniPID detector cell with anti-contamination design dramatically extends run time in the field. Low cost filters and lamps can be easily changed in minutes, minimising downtime.

It features long life rechargeable Li-ion batteries which give up to 24 hours usage. Fast battery charging allows the instrument to be fully charged in 6.5 hours, while eight hours of use can be achieved from 1.5 hours of charging time.

It features a protective, removable boot for harsh environments while a large, clear back-lit display allows for easy viewing in any light condition. It is IP 65 rated against water ingress. An integrated torch is designed for directing the instrument’s probe into dimly lit areas. Other features include a loud 95 dB audible alarm and multiple language support. Ready to use, straight out of the box, the instrument does not require complicated set up procedures via a PC to perform basic functions.

Risk assessments of on-site contamination.

IGE Consulting, is using a Tiger^LT handheld photoionisation detector (PID) from Ion Science – leading global manufacturer of high-performance gas detection instrumentation for environmental or occupational health applications – to provide comprehensive risk assessments of on-site contamination.

Supplied by Shawcity, the instrument was chosen for its flexible lamp design options that target different ranges and types of gases, and is monitoring potentially dangerous volatile organic compounds (VOCs) in soils which may cause harm to human health or compromise safety.

IGE Consulting undertakes desk studies and intrusive site investigation works on sites to be developed into residential or commercial developments. The company operates across Britain and provides a tailored service to meet client requirements such as pre-acquisition / planning development, abnormal costing evaluations, site investigation works and construction efficiency savings.

Molly Brown, Geo-environmental Engineer at IGE Consulting comments: “We previously hired the Ion Science Tiger^LT  for monitoring VOCs in soils so have used it numerous times with great success. To save costs in the long term, it made sense to purchase one of the instruments. It also adds value to our site investigations and reports as we are able to provide a more comprehensive risk assessment.

“One of the most appealing features of the TigerLT for us is the different options for lamps which allow various VOC gases to be detected. For example, we can choose lamps that give us a wide range or target specific ranges if we need to look for a particular type of VOC gas.”

The unit offers worldwide Intrinsic Safety (IS) certification for use in potentially explosive atmospheres, is a streamlined, low-cost version of Ion Science’s well proven Tiger PID model.

Like all Ion Science PID instruments, the Tiger^LT  incorporates the company’s market-leading PID technology with advanced patented fence electrode system. This three-electrode format ensures increased resistance to humidity and contamination for ultimate reliability and accuracy in the field.

With a detection range of 0.1 - 5,000 ppm utilising a standard two-point calibration protocol, it also offers an unrivalled industry response time of just two seconds and equally quick clear down.

Both simple to operate and service, the Tiger^LT  offers easy access to the lamp and sensor with batteries that can be safely replaced in hazardous environments. The intrinsically safe instrument also meets ATEX, IECEx, North American and Canadian standards.

Molly continues: “The Tiger^LT instrument is working well and enables us to provide a more comprehensive risk assessment of on-site contamination and the associated human health risk.
“In fact, the TigerLT PID instrument has already reduced costs for one of our clients by locating a VOC hotspot and proving blanks elsewhere on site meaning they did not have to install a VOC barrier on proposed plots. This client now only has to install VOC barriers on four out of 54 locations.”

The key advantage of Tiger^LT over other similar, low-cost handheld PID instruments is its market-leading accuracy and run time due to its anti-contamination and humidity-resistant design. Another attribute is its global Intrinsic Safety certification. Although the accreditation process can differ from country to country, the unit can be used in explosive hazardous areas such as within petrochemical plants that are located anywhere in the world.

The Tiger^LT six pin MiniPID detector cell with anti-contamination design dramatically extends run time in the field. Low cost filters and lamps can be easily changed in minutes, minimising downtime.

It features long life rechargeable Li-ion batteries which give up to 24 hours usage. Fast battery charging allows the instrument to be fully charged in 6.5 hours, while eight hours of use can be achieved from 1.5 hours of charging time.

Successful VOC detection.

Texas-based Lone Star Hazmat Response is using a handheld Tiger^LT volatile organic compound (VOC) monitor from Ion Science to identify the presence of potentially harmful VOCs at hazardous materials incidents. Chosen for its ease of use, quick start and humidity resistant design, the entry-level photoionisation detector (PID) is helping the emergency spill and land remediation specialist to increase efficiencies by quickly and accurately determining the level of protection required by first responders.

For more than 15 years, Lone Star Hazmat Response has excelled at providing industry-leading emergency spill response as well as safe and effective environmental remediation services. The company has steadily added to its capabilities and now maintains four strategically located rapid response centres in eastern Texas, which allows it to deploy rapidly whenever an emergency requires its services.

The Lone Star Hazmat Response team, which comprises hazmat specialists and incident commanders, works closely with first responders including firefighters, police and paramedics to provide critical support across a range of hazardous materials incidents. These include roadside emergency spills involving oil, diesel fuel and gasoline, product transfer for situations where fluid must be moved from a compromised vehicle to another or in the unfortunate event of an oil, gas or salt water release.

As part of its commitment to ensuring the safety of first responders, Lone Star Hazmat Response is using the Ion Science Tiger^LT PID to identify the presence of potentially harmful VOCs on scene and advise on the level of protection required.

Lone Star Hazmat Response uses PID instruments to quickly identify the presence of gases and vapours. Monitoring the ambient air for parts per million (ppm) and parts per billion (ppb) concentrations of VOCs allows the company to quickly evaluate the danger and determine if leaking fugitive gases are toxic.

Richard Lenius, General Manager at Lone Star Hazmat Response comments: “After meeting Ion Science at the TCEQ trade conference and learning more about its products, we chose the 
Tiger^LT handheld PID as it met our cost and functionality requirements. During testing the instrument proved extremely easy to operate and ready to use immediately after powering on. As we get called out to all kinds of environments, I was also particularly drawn to the instrument’s humidity resistance and anti-contamination design especially as our other PIDs had failed on humid days.”

This unit, which offers worldwide Intrinsic Safety (IS) certification for use in potentially explosive atmospheres, is a streamlined, low cost version of Ion Science’s well proven Tiger PID model.

Like all Ion Science PID instruments, the Tiger^LT incorporates the company’s market-leading PID technology with advanced patented fence electrode system. This three- electrode format ensures increased resistance to humidity and contamination for ultimate reliability and accuracy in the field.

With a detection range of 0.1 - 5,000 ppm utilising a standard two-point calibration protocol, Ion Science’s robust TigerLT also offers an unrivalled industry response time of just two seconds and equally quick clear down.

Although a PID is not specific in terms of gas selection, it offers a continuous and almost instant response rate enabling first responders to carry out their duties secure in the knowledge that their exposure to hazardous chemicals is limited.

“By its very nature, emergency response work carries an element of the unknown which can sometimes hinder our ability to quickly provide the vital information needed by first responders to ensure their own protection as well as that of bystanders and the wider community,” Richard adds. “Even in the most challenging environments, a single PID like the Ion Science Tiger^LT gives fast, accurate and reliable results and a true reading rather than a percentage of mixed air.”

Both simple to operate and service, the Tiger^LT offers easy access to the lamp and sensor with batteries that can be safely replaced in hazardous environments. The intrinsically safe instrument also meets ATEX, IECEx, UL and CSA standards.

The key advantage over other similar, low cost handheld PID instruments is its market leading accuracy and run time due to is anti-contamination and humidity resistant design.

Richard continues: “The clear, back lit display with large font enables those members of the team that require glasses to see air readings better than the other PIDs we have used. It is
also quick and ready for use in comparison. One of the features that we particularly like is the quick button for zeroing the air.”

Tiger^LT features a protective, removable boot for harsh environments while a large, clear back-lit display allows for easy viewing in any light condition. It is IP 65 rated against water ingress. An integrated torch is designed for directing the instrument’s probe into dimly lit areas. Other features include a loud 95 dB audible alarm and multiple language support.

Ready to use, straight out of the box, the Tiger^LT does not require complicated set up procedures via a PC to perform basic functions.

Richard concludes: “Overall we have been really pleased with the TigerLT and the service provided by Ion Science. We would definitely recommend the instrument to other emergency hazmat response companies. In fact, I have already demonstrated the TigerLT to multiple fire department hazmat teams.”
