Karl Fischer titration FAQ, tips, tricks, and troubleshooting for KF titration. . You can also use it in volumetric titration, but here the drift level is normally not as stable as for coulometric titrations. This can result in variations in the results. A stabilization time can reduce such an effect. However, compared to the absolute water .The different ways of producing iodine can be divided into the coulometric method and the volumetric method. Karl Fischer Titration Principle. The KF reaction is based on an earlier reaction called the Bunsen reaction, in which sulfur dioxide is oxidized by iodine and consumes water in the oxidation process. The initial response is as follows:Volumetric Karl Fischer Titration is used for samples with a higher moisture content, while Coulometric Karl Fischer Titration is used for samples with a lower moisture content. Moisture content is an important parameter in many industries, including pharmaceuticals, food, and cosmetics. Moisture can affect the quality and stability of a .
