title: [Gas chromatography of alcoholic beverages].
abstract: The author carried out investigations on mixed fruit and grape brady obtainable in shops, as well as on the alcohol of the mixtures of 500 wine samples by means of gaschromatography, partly without preliminary preparation, and partly after extraction with ether and pentane respectively. It was established that the extraction method with ether and pentane accepted in the literature is suitable for the concentration of the side products of alcoholic beverages and thus for their gaschromatographic qualitative analisis as well. When examing higher alcohols - and also other side-products - the direct, examination without preliminary preparation must be given preference, because in this case there is also a possibility for quantitative determination. On the basis of his results the author considers an increased quality control of home distilled brandy necessary as well as the determination of alcohols of higher order, because in some cases he has detected a greater quality of fusel oil content than permissable (400 mg/100 ml albolute alcohol).
