Karl Fischer Buffers and Reagents

Buffers and reagents intended for use with Karl Fischer (KF) titration techniques. KF titration is a classic titration method that uses coulometric or volumetric titration to determine the moisture content of a sample.

Karl Fischer (KF) reagents are used in the analytical technique developed by chemist Karl Fischer to accurately measure the water content of gases, liquids, and solids.

Key applications include:

  • Analyzing water content in raw materials and finished products
  • Estimating moisture in food, pharmaceuticals, chemicals, and petroleum products
  • Determining the water content of laboratory samples.

Karl Fischer reagents contain a variety of chemicals in proprietary formulations. Consult the SDS for individual products for appropriate handling instructions and precautions.
