✦ Synopsis

Specific retention volumes of 12 solvents were measured at different temperatures on columns containing sucrose monopalmitate as their stationary phase. The influences of the temperature, adsorption effect in interface gas-liquid, and carrier gas flow on the chromatographic retention were analyzed. Henry's constants were calculated and the solubilities in the surfactant were obtained. The results were analyzed by the combination of Flory-Huggins and Hildebrand theories, and the solubility parameter of surfactant was obtained at different temperatures. The relation between solubility parameter and hydrophile-lipophile balance was discussed.

Inverse gas chromatography (IGC) is a versatile tool for the characterization of porous solids. IGC at finite dilution has historically been used for isotherm measurements because of fast equilibration times. A combination of IGC with a flash thermodesorption method allows the separation of micropor
