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.
This Application Bulletin gives an overview of the volumetric water content determination according to Karl Fischer. Amongst others, it describes the handling of electrodes, samples, and water standards. The described procedures and parameters comply with the ASTM E203.For volumetric Karl Fischer titration, there are mainly two types of reagent. One component KF reagent: Iodine, sulfur dioxide, and imidazole are all present in the titrant and are dissolved in appropriate alcohol. Methanol serves as a solvent. With the one-component reagent, titration speed is slower. But this regent is easy to handle.
Thus, the optimal pH range for the Karl Fischer reaction is from 5 to 8, and highly acidic or basic samples need to be buffered to bring the overall pH into that range. What are the two types of Karl Fischer Titration? 1) Volumetric KFT In volumetric Karl Fischer, iodine is added mechanically to a solvent containing the sample by the
