Hydranal FA (free of alcohols) reagents – new solution for challenging alcohol sensitive samples





Hydranal™ NEXTGEN Coulomat A-FA & C-FA are the first alcohol-free reagents for Karl Fischer (KF) titration that avoid side effects and provide consistent results for many challenging alcohol-sensitive samples. 

The KF titration of certain types of samples, like ketones, can be challenging, due to the side reactions of these compounds with alcohols. Such challenges include erroneous water content results, and unstable, vanishing or no titration endpoints (see Fig. 1). The new Hydranal™ NEXTGEN FA (free of alcohol) reagents avoid many such side effects and allow for accurate water content determination, even in difficult samples. with lower drift increase and higher sample capacity (see Fig.2).  Additionally, these reagents allow the titration of many unsaturated compounds with double and triple bonds like vinylene carbonate, vinyl acetate, allyl acetate, or propynyl derivatives. These reagents are also safer, as they do not contain CMR (carcinogenic, mutagenic and reprotoxic) substances or halogenated hydrocarbons. 

NOTE: There is no need to develop new analysis methods when upgrading to Hydranal FA reagents. An official statement can be found here
