Next month (June 2010) Endress+Hauser is to launch its new generation of automatic samplers for liquid analysis worldwide. The stationary Liquistation CSF48 sampler and the portable Liquiport 2010 CSP44 version will revolutionise the world of sampling. They not only fulfill all international standards and laws, they also offer a unique level of flexibility for water-related applications. Furthermore, they are based on the new Liquiline-Memosens platform and can therefore be used as complete measuring stations.
Focus on flexibility
The core principle of our new analysis platform is ensuring that identical tasks are always carried out in an identical manner – to provide the customer with a high level of flexibility and simplicity. This platform concept also makes it possible to easily extend the sampler into a measuring station without needing to connect additional transmitters. Thanks to the flexible electronics and expansion slots, inputs for digital sensors with Memosens protocol can be added via plug-and-play. The sensors are automatically detected by the software and can therefore be put into operation easily. Product manager Karlheinz Bareiss proudly explains, "For the first time, one device can perform both tasks - take samples and simultaneously measure various parameters such as pH, turbidity, conductivity or nitrate content".
User-friendly, simple operation
The new sampler features the same clearly arranged operation concept as the rest of the Liquiline platform. The menu depth has been kept to a minimum to allow fast navigation, and the large graphical display guides the user through the software with its 9 lines, each 45 characters long. The sampling programs provide maximum flexibility and cater to all requirements – starting at the "Basic" program with just 5 inputs and ranging up to the "Standard" and "Advanced" programs whereby up to 24 sub-programs can be linked to each other. "The convenient navigator and 4 soft keys make entering the measured values and programs as easy as operating a pocket calculator or mobile phone", says Mr. Bareiss.
Modular housing with extra security
The modular housing consists of two parts with separately lockable doors to ensure that samples are always stored securely. Further protection is provided by the design, with no screws on the outside of the housing. Once locked, the sampler cannot be broken open. Great emphasis was also placed on the stability of the housing materials. In addition to the familiar V2A and V4A stainless steels, 2 plastic versions have been developed - polystyrene for use in all standard applications at wastewater treatment plants and ASA-PC (Luran®) for external use. ASA-PC is the plastic with the best characteristics for UV resistance, thermal stress, mechanical stress, insulation and chemical resistance.
Perfect sample preparation for laboratory analysis
The innovative power supply and cooling system ensure that the samples are not exposed to any fluctuations in temperature and therefore cannot undergo change. The power supply has primarily been designed for 24 VDC in order to cope with worldwide variations in mains voltage and mains frequency, and in order to meet safety requirements in every part of the world.
No overly heavy bottles, no back problems – the unique, dual bottle trays make it easier to transport samples to the laboratory. They meet all of the guidelines of the occupational accident prevention and insurance association. The dual trays also allow simultaneous use of individual bottles and containers in one device (e.g. 12 x 1 litre + 2 x 13 litres). This is particularly advantageous when "alarm samples" need to be taken and filled into special containers when specific events occur e.g. if the pH value is too high. The bottle configuration is also completely flexible in terms of the bottle materials. PE and glass bottles can both be used, ensuring perfect operation with any medium and guaranteeing compliance with DIN/IEC standards.
