Lambda Advanced Technology has announced the availability of the Easywater (EasyH2O) analyser, designed for the specific determination of water.
Applications for the Easywater system include materials such as plastics, catalysts, pharmaceuticals, building materials and more.
The system uses a proven thermo-coulometric measurement method, providing an environmentally friendly, chemical-free alternative to the Karl Fischer titration technique.
The Easywater system specifically measures water and not other volatiles such as alcohols, oils or fats.
It can also differentiate between different binding phases ranging from free surface and capillary water to chemically bound water.
Lambda Advanced Technology said the analyser combines thermal evaporation of water with a selective, electrochemical sensor to create an innovative method of water analysis.
The water content of various materials frequently has a significant impact on the material characteristics.
Examples include the injection-moulding behaviour of plastics, the stability of active pharmaceutical agents or the actual price of raw materials.
The water is evaporated from the sample in a programmable oven and is fed to the sensor using a stream of dried ambient air as a carrier gas.
This means that no expensive or toxic chemicals or carrier gases are required for operation.
By varying the temperature profile of the heating program, different forms of water can be selectively evaporated and differentiated.
Even strongly bound water is released and quantified via temperature programs up to 400C.
The coulometric sensor uses an electrochemical reaction to produce an absolute measurement and deliver reproducible, accurate results.
The method is well established and used in international standards DIN 50450-1, ASTM D 5454 and ISO 11541:1997.
The measuring cell regenerates itself and the system is permanently rinsed with dried air, ensuring the analyser is always ready for use.
The entire process runs automatically under software control.
All of the data, temperature programs, and so on are logged in compliance with ISO and GLP and can be printed or read-in again.
