In this work, the dependences of the retention time of organic substances (aromatic hydrocarbons, C₁₀-C₁₄ alkanes and n-aliphatic alcohols) at 150 ^oC temperature on the concentration of Apiezon L brand lubricant, and of the polar liquid phase of poly-ethylene glycol adipianate are specified. It is shown that the dependence of the corrected retention time of organic compounds (n-xylene, mesitylene, durol) for various mobile phases (nitrogen, hexane, ethyl alcohol) is almost linear. The dependence of the retention time on the boiling point of aromatic hydrocarbons at 150 ^oC temperature on the nature of the mobile phase (nitrogen, hexane, ethyl alcohol) and on the percentage of the polar liquid phase of polyethylene glycol adipianate (2–15 %) is linear.
