FIELD: chemistry.
SUBSTANCE: invention relates to a method of preparing bioorganic samples, including medical samples, for determination of the isotope ratio 14C/12C and 14C/13C in the samples using an acceleration mass spectrometer. The method of preparing bioorganic samples, including medical samples, includes oxidising carbon contained in a bioorganic sample to carbon dioxide. The bioorganic sample is oxidised in liquid phase; the oxidising agent used is hydrogen peroxide and the catalyst used is a ZSM-5 type zeolite with an iron-containing active component. The carbon dioxide CO2 released during oxidation is then graphitised and the obtained powder is pressed.
EFFECT: wider range of substances analysed for isotopic abundance of carbon using an acceleration mass spectroscopy.
