The correlation between the RM-values measured in both adsorption and partition chromatography have been investigated for a number of substances such as heterocyclic bases, naphthols, naphthylamines, and isomeric nitroanilines. Aluminium oxide G, silica gel G, and magnesium silicate were used as the adsorbent and formamide, ethylene glycol, and a pH=2.4 buffer as the liquid stationary phase. Eleven solvents served as the mobile phase. It was found that for all compounds investigated the function\(R_{M_i } = f{\text{(}}R_{M_i }^p )\) is represented by a linear relationship corresponding to the equation\(R_{M_i } = aR_{M_i }^p + b\). The constants a and b are characteristic for a compound in a given system of stationary phases (adsorbent and partitioning liquid).
