A mechanism of the solute retention in gas-liquid chromatography has been studied in the nonpolar hydrocarbon solute-polar stationary liquid phase system. N, N, N′, N′-tetrakis(2-hydroxyethyl)ethylene diamine (THEED) was used as a polar stationary liquid phase. A dependence of the retention volume of the solutes and of the specific surface area of the liquid-coated, modified alumina upon the liquid loading was successfully interpreted on the basis of a previous model for distribution of the liquid phase on the modified alumina. The appearance of a maximum on the retention volume vs. liquid loading curve for the saturated hydrocarbon can be understood as a formation of the 1:1 solute-THEED adduct through the lateral interaction between the two molecules adsorbed on the modified alumina.
