Karl Fischer titration method

The Karl Fischer titration method is a technique that uses chemical reactions to quantify the moisture content in a sample.

- It is possible to quantify water in the range of several ppm to several percent. - Solid samples that do not dissolve in the electrolyte can also be quantified.
