The Karl Fischer titration (KFT) is an analytical technique for the water determination in food, pharma, petrochemical, and other samples. The water content is measured as an important quality parameter of several goods. While in food and pharma the water content has an important influence on the expiry date/stability of the final product, the water content of crude oil determines the price of this heavily used raw material.
By applying KFT, moisture and crystal water are determined all together. This can be done by carrying out volumetric or coulometric KFT. Volumetric KFT is applicable to solid and liquid samples with water content greater than 1%, while coulometric KFT is used only in liquid samples with water content smaller than 1%.
AQUAMETRIC® is the in-house produced range of pyridine-free Karl Fischer reagents and applicable for volumetric and coulometric KFT. AQUAMETRIC® is a complete solution for all laboratories carrying out water determinations using KFT, and consists of water standards, working media and dried solvents.
