FIELD: chemistry.
SUBSTANCE: described is an alcohol thermal hydration chamber and an apparatus for real-time determination of isotopic composition of non-exchangeable hydrogen and deuterium atoms in ethanol samples, comprising: A) an alcohol thermal dehydration chamber, B) an indicating device which has a pyrolysis reactor (26) and a continuous flow isotope spectrometer and is connected to the alcohol thermal dehydration chamber by C) a system of valves, connectors and capillary tubes which are used to transfer the analysed sample and clean the alcohol thermal dehydration chamber; the procedure for real-time determination of isotopic composition of non-exchangeable hydrogen and deuterium atoms in ethanol samples and the procedure for off-line preparation of ethene (ethylene) gas by means of the alcohol thermal dehydration chamber and for the identity and geographical origin of wines, alcoholic beverages, fruit juices, honey and etc.
EFFECT: high accuracy of determination.
