Abstract: The method of gas chromatography-mass spectrometry was applied to study the distribution of hydrocarbons of diamond-like structure — the triamantans C18-C19 -in oils and condensates of Kalmykia, occurring in the Cretaceous and Jurassic sediments. It is shown that extraneous peaks present in the mass chromatograms of paraffin-cyclo-paraffinic petroleum fractions with 240 and 239 m/z do not interfere with the identification and calculation of triamantans and calculation of their relative concentrations. We found that the Jurassic and Cretaceous oils are possible to distinguish between by relative distribution of C18 triamantan.
