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.
