Karl Fischer Reagents for Moisture Analysis

Karl Fischer Titration (KF, or KFT) is the leading method for measuring water content in a wide variety of products and industries, such as Chemicals, Petroleum Products, Foods, Pharmaceuticalsm and many others. There are two primary types of KFT - Volumetric and Coulometric.

Volumetric KFT is typically recommended for moderate-to-high water content determination in the range of 0.1% to 100%. On the other hand, Coulometric KFT is utilized for determination of water at very low levels, typically well below 1%. Most modern volumetric and coulometric reagents are characterized by high titration rates and produce accurate, reliable results.

In addition, Standards and Reference Materials are required to ensure accurate, precise, and reproducible titration results. Both solid and liquid standards with varying certified water contents are used for monitoring and qualification of KF instrumentation.

VWR's portfolio includes a wide variety of KFT reagent and standard types, all produced under exacting quality control using validated procedures for highest possible accuracy and precision.
