What is Coulometric Karl Fischer Titration?
German scientist Karl Fischer developed the Karl Fischer Titration (KFT) technique to find sample water content. Two primary forms are volumetric and Coulometric. Usually between 1 ppm and 5%, Coulometric Titration creates the titrant electrolytically, ensuring great accuracy for lower water content measurements while volumetric titration employs a titrant reagent provided in a quantifiable volume.

Basics of the Karl Fischer Reaction
The primary reaction involved in Karl Fischer Titration is:
[ \text{I}_2 + \text{SO}_2 + 2\text{H}_2\text{O} \rightarrow 2\text{HI} + \text{H}_2\text{SO}_4 ]
Usually using an alcohol as a solvent, this reaction occurs in a solution including iodine, sulphur dioxide, and a base. The consumption of iodine exactly corresponds to the water content.
How Coulometric Karl Fischer Titration Works
How Coulometric Karl Fischer Titration in Coulometric For low moisture samples, Karl Fischer Titration—where iodine is produced in situ by electrolysis—makes great sense. The thorough series of actions consists in:
Step 1: Sample Introduction
The pre-made reactant combination in the titration cell is inserted with the sample.
Step 2: Electrolytic Generation of Iodine
The cell passes an electrical current electrolytically producing iodine from iodide.
Step 3: Reaction with Water
The produced iodine interacts with the water from the sample. Until all the water has reacted, the continual generating and reaction keep on.
Step 4: Endpoint Detection
Once all the accessible water has reacted, the end point—which exactly indicates the water content—is recognised by a drop in the electrical current.
Advantages of Coulometric Karl Fischer Titrators
High Sensitivity
Coulometrics Perfect for exact readings, Karl Fischer Titrators are very sensitive and able to detect water content as low as a few parts per million (ppm).
Automation
