A Karl Fischer titrator. In analytical chemistry, Karl Fischer titration is a classic titration method that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. [1] [2] Today, the titration is done with an automated Karl Fischer titrator.
When it comes to measuring the water content of a sample, the Karl Fischer method is widely regarded as the best option. A comprehensive approach involving volumetric and coulometric Karl Fischer titration is provided to determine the water content in polyols. Both techniques have been shown to produce consistent results.application of the volumetric Karl Fischer (KF) titration for determining free water and water of hydration in most solid or liquid organic and inorganic compounds.
