HYDRANAL – Coulomat CG-K is a coulometric Karl Fischer titration reagent (catholyte) specially formulated for water content analysis in ketone samples, and is designed to be methanol-free. This product is part of the HYDRANAL reagent series manufactured by Honeywell Fluka for Karl Fischer titration.
Karl Fischer Titration:
Karl Fischer titration is a volumetric or coulometric analytical method used to determine the water content in various types of samples.
Coulometry:
In coulometric Karl Fischer titration, water reacts with the Karl Fischer reagent (iodine, sulfur dioxide, and a base), which is generated electrochemically within the titration cell.
Catholyte:
HYDRANAL – Coulomat CG-K acts as the catholyte, a component of the titration cell that functions as the electrolyte, providing the ions necessary for the redox reaction.
Methanol-Free:
The special methanol-free formulation of Coulomat CG-K allows it to be used in the analysis of ketone-containing samples, which are often incompatible with methanol-based reagents.
Applications:
This product is suitable for water content analysis in various types of ketone samples, including those that are volatile or reactive, and thus difficult to analyze.
