The pyrolytic gas chromatography method is widely used in the study of polymer materials, plastics, rubbers, rubbers, paints and other high-molecular compounds of natural and artificial origin. The method is based on thermal decomposition of sample samples in an inert medium (without oxygen access), followed by chromatographic separation and analysis of the formed volatile compounds.
