HYDRANAL-Coulomat AG is a reagent used in Karl Fischer titration, specifically for the coulometric method, which is employed to determine water content in various types of samples. This reagent is typically an anolyte solution used in titration cells, both with and without a diaphragm.
Karl Fischer Titration (KF):
This is a highly accurate volumetric or coulometric analytical method for determining the water content in a wide range of samples, from solids to liquids.
Coulometric Method:
In coulometric titration, the iodine required for the reaction with water is generated electrochemically within the titration cell. HYDRANAL-Coulomat AG is one of the reagents used in this process.
Anolyte:
This reagent is commonly used as the anolyte, the part of the titration cell that contains the reagent that reacts with water. Other reagents, such as HYDRANAL-Coulomat CG, are used as the catholyte.
Cells With and Without Diaphragm:
HYDRANAL-Coulomat AG is suitable for use in KF titration cells both with a diaphragm (which separates the anolyte and catholyte) and without a diaphragm.
Base Composition:
This reagent is typically methanol-based.
Applications:
It is suitable for a wide range of water content analysis applications, including oil samples and non-polar samples, especially when used with special solvents.
