Endress+Hauser’s Liquistation CSF48 and Liquiport 2010 CPS44 are automatic samplers and measuring stations in one.
Endress+Hauser’s new generation of automatic samplers for liquid analysis – Liquistation CSF48 sampler and the portable Liquiport 2010 CSP44 version – offer unique flexibility for water-related applications as they are based on the Liquiline-Memosens platform and can therefore be used as complete measuring stations.
Focus on flexibility
The principle of the new analysis platform is to ensure that identical tasks are always carried out in an identical fashion for a high level of flexibility and simplicity. This concept also makes it possible to extend the sampler into a measuring station without the need for additional transmitters. Due to its flexible electronics and expansion slot inputs digital sensors with Memosens protocol can be added via plug-and-play. The sensors are automatically detected by the software and are operational almost immediately. One device can now both take samples and simultaneously measure parameters such as pH, turbidity, conductivity and nitrate content.
User-friendly 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 a large graphical display guides the user through the software. The sampling programs provide maximum flexibility for all requirements – starting at the ‘Basic’ level with five inputs through the ‘Standard’ to the ‘Advanced’ program where up to 24 sub-programs can be linked. “The convenient navigator and four softkeys make entering the measured values and programs as easy as operating a pocket calculator or mobile phone,” says E+H liquid analysis product manager Jan Swart.
Modular housing provides extra security
The modular housing consists of two parts with separately lockable doors to ensure that samples are always stored securely. Emphasis was also placed on the stability of the housing materials. In addition to the familiar V2A and V4A stainless steels, two 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 and mechanical stress, insulation and chemical resistance.
Sample preparation for laboratory analysis
The innovative power supply and cooling system ensure that samples are not exposed to fluctuations in temperature which could change the characteristics. Dual bottle trays have been provided to make it easier to transport samples to the laboratory. The dual trays also allow simultaneous use of differing bottles and containers in one device (eg, 12x1 litre + 2x13 litre). This is particularly advantageous when ‘alarm samples’ in special containers need to be taken in response to a specific event eg, if the pH value gets too high. The bottle configuration is also flexible in terms of the bottle materials. PE and glass bottles can both be used in compliance with DIN/IEC standards.
