Sample Preparation for Karl Fischer Titration, KF Guide 2

Mettler Toledo Group, Laboratory Division, 2017. — 32 p.The Karl Fischer method determines water content specifically and is easily applied to a huge variety of samples. It is a common standard method in R&D, quality control and production monitoring.
However, the method requires adequate sample preparation in order to release entrapped, capillary-bound or water of crystallization. The water molecules need to be ’freely available’ in order to undergo the chemical reaction with the KF reagents.
This brochure uses METTLER TOLEDO’s expert knowledge of Karl Fischer titration to explain more advanced sample preparation procedures than the simple sample dissolution in the titration cell.
Apply these well-proven applications to your samples for quick, simple and accurate water content titrations.
