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 .
