Abstract: A method for determining the sojourn time of adsorption of gas on solid surface by gas chromatography is presented. A theoretical equation has been derived. The method has been verified by the experimental adsorption data of eight alkanes and benzene on silica gel. And satisfactory results were got.

Key words: Sojourn time of adsorption, Vibration time of adsorption, Gas chromatography, Gas-solid surface
