Chemical method to determine trace amounts of water in a sample
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.
