Gas-solid adsorption chromatography (GSC) is an attractive method for studying physicochemical properties of adsorbents and catalysts including characterization of their adsorbent heterogeneity. A new equation for the total net retention volume is used to describe pressure-dependent retention measurements for cyclohexane and cyclohexene on wide-pore and narrow-pore silicas. This equation gives a good representation of the above experimental data. Parameters of this equation permit evaluation of the distribution functions that characterize the energetic heterogeneity of solid adsorbents.
