Abstract: A new system for the determination of binary gas solid adsorption isotherm with chromatography was established.The system was composed of the frontal chromatographic adsorption system and the chromatographic quantitative analysis system.After the equilibrium of the adsorbed phase and the gas phase had arrived in the adsorption system,these components were injected into the analysis system with the carrier gas and were determined respectively by turning the switch valves.The major factors which had an effect on the measurement were discussed at full length.

Key words: Binary gas solid adsorption, Adsorption isotherm, Frontal chromatography
