By use of Karl Fischer titration Norner can decide the moisture content of polymers.
Several polymers are hygroscopic, and it is especially important to control and understand their moisture content before processing them. Also for other polymers it can be relevant to analyse.
Determination of water content is done on a by vaporization in a heating oven in nitrogen gas followed by a Karl Fischer coulometric titration of the collected water.
The determination of water content follows the ISO 15512-2008 methodology.
