The presented review is devoted to methods for determining the component composition of the studied catalytic reactions, natural gas and its processed products using gas chromatography columns prepared on the basis of poly(1-trimethylsilyl-1-propyne) polymer (PTMSP). Methods of polymer modification are proposed in order to change the polarity and selectivity of separation of compounds of different chemical nature. The influence of the film thickness of the PTMSP stationary phase on the separation parameters and the loading capacity of the columns used is noted. Examples of the use of packed and capillary columns in solving various problems by gas chromatography are shown. The detection limits are determined and the repeatability for the analyzed compounds are calculated.
