Fluka™ HYDRANAL™ Coulomat CG-K is a methanol-free catholyte reagent designed for coulometric Karl Fischer titration of ketone-containing samples. Conventional methanol-based Karl Fischer reagents can react with ketones to form ketals, which may interfere with accurate moisture determination. Coulomat CG-K eliminates this issue by using a methanol-free formulation optimized for ketone compatibility.
The reagent is used in the cathode compartment of Karl Fischer titration cells, working together with compatible HYDRANAL™ anolyte reagents such as Coulomat AK. This combination enables reliable electrochemical conditions for precise trace moisture analysis in reactive or sensitive organic compounds.
As part of the HYDRANAL™ Karl Fischer reagent range, Coulomat CG-K provides consistent analytical performance and reliable moisture determination for laboratories analyzing ketones, aldehydes, and other reactive solvents.
