Identification of Vodkas by Ion Chromatography and Gas Chromatography

Vodka samples from various distilleries were analyzed by ion chromatography in combination with gas chromatography for the identification of alcoholic products. It was shown that vodkas of the same name manufactured at the same distillery exhibited relatively stable anion–cation compositions; therefore, the ionic composition of vodka can serve as an identification feature. The use of methanol, 2-propanol, and 1-propanol concentrations, which were determined by gas chromatography, as identification features of vodka enhances the probability of detecting adulterated alcoholic products.
