Capillary gas chromatography is the main method for analysing volatile compounds in science, industry and environmental control in many spheres of human activity [1, 2]. Capillary gas chromatography is used particularly actively in petroleum chemistry, scientific research and in industry. The development of physicochemical principles of chromatography and a better understanding of the process are therefore of theoretical and practical importance. The main participants in GLC are firstly the stationary liquid phase (SLP) together with the solid support, secondly the substances to be separated (or the sorbates), and thirdly the mobile phase or carrier gas.
