A method for identifying straits of rocket kerosene (RG-1 and T-1 brands) and various types of hydrocarbon fuels in the soil (aviation fuel ТС-1 and diesel fuel) has been developed. The proposed variant of identification is based on the preliminary separation of the main components by gas chromatography and their mass spectrometric detection, and processing of the obtained data with chemometric methods of analysis (principal component analysis and projection on latent structures with discriminant analysis) using the programs «MZmine2», «iMet-Q» and «MetaboAnalyst». The opportunity of application of the developed approach for the typification of saturated fractions of oils from different origins is illustrated.
