General information

Coulometric Reagents

Karl Fischer coulometric titration is suitable for substances with a low water content (i.e. <0,1 %) and, for example, for expensive substances that can only be examined in small quantities.


In the coulometric titration process, the iodine required is produced directly in situ at the electrode in the reaction vessel through the anodic oxidation of iodide. Hydrogen is produced at the cathode. The measuring cell contains an anode and cathode chamber, which can be separated by a diaphragm. This means that the titration cell can be equipped with diaphragms or be diaphragm-free.

Carl ROTH offers suitable reagents for both models.


Table illustrating the uses of Karl Fischer Roti®Hydroquant coulometric reagents:

coulo CG (9861) coulo CG-K (1KPP)

coulo A (9957) X for cells with diaphragms.

coulo Oil (9960) X for cells with diaphragms.

coulo AK (1KPN)

X for cells with diaphragm, for aldehydes and ketones.

coulo AD (1KPL)

Can be used without additional reagents. For cells without diaphragms.
coulo AG (9854)

Can be used without additional reagents. For cells without diaphragms.

Standards

Water standards with a defined water content are required to determine the titre for the reagents used. Either a solid or a liquid standard can be chosen.
