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.
