Whatever your requirements – we have the right Karl Fischer titrator for you Our portfolio of Karl Fischer titrators includes compact all-in-one options for routine moisture determination as well as fully automated Karl Fischer systems for volumetric and coulometric Karl Fischer titration of water contents from 0.001 to 100%.
MM: We recommend carrying out a volumetric or coulometric Karl Fischer titration using a certified standard as a sample. In volumetry, a threefold titer determination followed by a determination of a different standard is carried out and the recovery of the water content in the determination of the standard is calculated.
This blog article explains the most important factors to consider in order to choose the optimal Karl Fischer titration technique: coulometry or volumetry. Coulometric Karl Fischer titration (KFC) is generally used for samples with a low moisture content between 0.001% to 1%. Volumetric Karl Fischer titration (KFT) is used for samples with higher levels of moisture .
