Karl Fischer titration Generally, KF is conducted using a separate KF titrator or for volumetric titration, a KF titration cell installed into a general-purpose titrator. Using volumetric titration with visual detection of a titration endpoint is also possible with coloured samples by UV/VIS spectrophotometric detection. Karl Fischer titration Karl Fischer titration is a classic titration method in analytical chemistry 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. Today, the titration is done with an automated Karl Fischer titrator. The main compartment of the titration cell
