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.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
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.• Titrator with a mode for volumetric Karl Fischer titration • Analytical balance (minimum resolution 0.1 mg) Accessories • Plastic or glass syringe and 6needle with a thickness of approx. 0.8 mm (for liquid standards) • Glass weighing spoon (for solid standards) Karl Fischer titration is the most widely used technique to determine the water content in a sample.
