Most operators who measure moisture using a Volumetric Karl Fischer Titrator tend to have difficulty in 3 areas. Unlike Coulometric Karl Fischer Titrators where the equipment setup and reagents are fairly straight forward, Volumetric Karl Fischer Titrators differ greatly. Understanding how a Volumetric Karl Fischer Titrator differs and how the .Volumetric titration. The volumetric titration is based on the same principles as the coulometric titration except that the anode solution above now is used as the titrant solution. The titrant consists of an alcohol (ROH), base (B), SO 2 and a known concentration of I 2. One mole of I 2 is consumed for each mole of H 2 O. The titration .In the pharmaceutical industry, Karl Fischer titration is used for the determination of water content in various drugs and excipients.The method is efficient, rapid, and accurate and provides reliable results. It allows the quantification of water content in samples ranging from ppm to 100%.
1. There are now three model levels; entry, mid-level, and flagship within each category (volumetric Karl Fischer, coulometric Karl Fischer, and automatic potentiometric titrator) My comment: I like the scale of the models as it can be helpful for those with varied budgets and needs.
