Abstract: The characteristics of multicomponent chromatography with mobile micellar phase were analyzed by the theory of coherence and the concept of multiphase chromatography.The feature of such chromatographic process was significantly affected by both the extraction of solutes by the micellar phase from the aqueous phase and the adsorption of solutes on the stationary phase.If the extraction was predominant for the adsorptive solute, the competition effect between adsorption and extraction resulted in inversion points in the chromatographic process.The sequence of solutes flowing from the chromatogram would be changed at the inversion point, and so would the entropy condition.Although the existence of inversion points increased the complexity of the chromatographic process, it provided alternative chromatographic operations.
