The influence of mixed micellar systems on retention and selectivity in micellar electrokinetic chromatography is examined using linear solvation energy relationships (LSER). Systems that were investigated include mixed bile salts [sodium deoxycholate (SDC) and sodium cholate (SC)] and mixed sodium dodecyl sulfate (SDS)–bile salt systems (e.g., SDS–SC and SDS–SDC). The retention behavior in individual and mixed micellar systems is primarily determined by size and hydrogen bond acceptor strengths of solutes. Through a comparative study of the LSER coefficients in the individual and mixed micellar systems, it was concluded that hydrogen bonding interactions have a significant effect on selectivity of these pseudostationary phases in electrokinetic chromatography. The interactive properties of the mixed micelles are different from the constituent individual micelles, however, the overall characteristics are closer to one of the bile salt micelles in the mixture even at the equimolar compositions.
