Results are presented of structural studies of a silica-based surface-porous adsorbent. It is shown that a reliable estimate of the size of the surface micropores of this adsorbent can be obtained using the gas chromatographic version of the molecular probe method. This is based on a comparison of the thermodynamic properties for the adsorption of substances of known molecular size on the surface-porous adsorbent with those characteristic for the adsorption of the same substances on to a non-porous adsorbent of a similar chemical nature.
