easyH20 Chemical-free Water Determination.
The Berghof easyH2O combines thermal evaporation of water with a selective, electrochemical water sensor to a new and innovative method of water analysis. Unlike the gravimetric moisture-measuring techniques, the result is not disturbed by substances which evaporate out of the sample together with the water. It therefore delivers reproducible, accurate results and facilitates separate identification of free surface and capillary water as well as bonded water.
The water is evaporated out of the sample in a programmable oven and is fed to the sensor by a carrier gas. The coulometric sensor based on hygroscopic phosphorous pentoxide absorbs the water. The water is electrolysed immediately and the required electrical charge is proportional to the quantity of water which is determined. Thus the sensor regenerates itself and is always ready to use. Operation is extremely simple. No special or toxic chemicals are required to operate the system. The operator profits by reduced operating and disposal costs as well as reduced blank value input regarding chemicals.
Influence of Water Content on the Processability of Polyesters
The presence of water in plastics has a substantial influence on the quality and processability of the end products, particularly in the consumer sector. Therefore, quality control procedures are required that allow for simple and fast determination of the water content. This application note demonstrates the use of the Berghof Easy H2O one water determination system, which combines the thermal evaporation of water with a selective electrochemical water sensor to easily determine water content in plastics.
