The additive absorption-adsorption retention theory gave the possibility quantitatively of studying important processes and relationships in gas-[liquid-solid] chromatography-for example, the asymmetry of chromatographic zones [37], the dependence of the retention indexes in capillary chromatography on the sample volume [38], the modification of the internal surfaces of capillary columns [39-42], the enrichment of the trace amount of pollution [43], the aging [44-46] of capillary columns with volatile phase [e.g., with 1,2,3-tri(cyanoethoxy)propane], and the application of zero indexes [47].
