What is volumetric Karl Fischer titration?

Karl Fischer titration is a method for moisture determination that is specific to water. As opposed to other methods, such as drying ovens or infrared lamps, Karl Fischer titrators determine the actual water content in a sample, whereas other methods determine all volatile components that evaporate under the influence of heat.

One of the main benefits of Karl Fischer titration is that the water content determination typically takes only a few minutes, compared to up to several hours for drying techniques.

Karl Fischer titration is a well-established and widely applied analytical method. For example, it is the reference method mentioned in many national and international standards applied in all industries.
