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 .Karl Fischer (KF) titration is a widely accepted method for determining the water content in a sample, with volumetric Karl Fischer titration being the most used technique, measuring water content from 100 ppm to 100%. However, achieving accurate results can be challenging, as several factors can influence the outcome. .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%. I recommend carrying out a volumetric or coulometric Karl Fischer titration using a certified water standard as sample. In volumetry, you can carry out a threefold titer determination followed by a determination of a different standard. Then, you can calculate the recovery of the water content determination of the standard.
