HYDRANAL – Coulomat A is a reagent used in Karl Fischer (KF) coulometric titration, specifically as an anolyte (positive electrolyte solution) in titration cells with or without a diaphragm. It is methanol-based and used to determine the water content in various samples.
Karl Fischer Coulometric Titration:
Coulomat A is used in the Karl Fischer titration method, which is a specialized technique for determining the water content in a substance.
Anolyte:
In the context of coulometric titration cells, Coulomat A functions as the anolyte, the electrolyte solution located on the positive side of the cell.
Cells with/without Diaphragm:
Coulomat A can be used in KF titration cells whether or not they are equipped with a diaphragm (separator).
Methanol-Based:
This reagent is formulated with methanol as its primary solvent.
Applications:
Coulomat A is used in a variety of coulometric KF titration applications, particularly for determining water content in different types of samples.
