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.
METTLER TOLEDO's Karl Fischer titrators offer volumetric methods for water determination up to 100% and/or coulometric methods for low water content from 1 ppm to 5%. The titration vessel is made completely of glass which ensures exceptionally low drift, making the most accurate and precise results possible.The Volumetric Compact Karl Fischer Titrators have been designed for a wide range of water content applications: determinations from 100 ppm to 100% water – fast and precisely. The titration vessel is optimized to retain a low drift value and offers the possibility to determine the water content .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
Titer determination in volumetric Karl Fischer titration. 1. Liquid water standard. For the addition of a liquid water standard, you need a syringe and a needle. There are two possibilities to add liquid standard. One is to inject it with the tip of the needle placed above the reagent level. In this case, aspirate the last drop back into the .
• 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. It is used in the analysiz of foods, pharmaceuticals and many chemicals, among others.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. 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 .
