Summary
The present paper deals with the applicability of the equation relating RM values of the solute to the composition of a two-component liquid mobile phase. Dependence of the above factors on the porosity of silica gel adsorbents, used as a stationary phase, was examined. The examinations were carried out on adsorbents with pore diameters ranging from 60 to 1000 Å. The mobile phase was a two-component solvent mixture: carbon tetrachloride — acetone. A number of aromatics were used as model solutes. The examinations showed that the porosity of silica gels when using two-component solvent mixtures which are conformal solutions as the mobile phase, has no influence on the agreement of the theoretical and experimental\(R_{M_{1,2} } = f(\varphi _1 )\) functions. A fairly good agreement was obtained between the theoretical and experimental data.
