Summary Retention models for ionic compounds in reversed-phase ion-pair chromatographic systems have been developed on the basis of the capacity ratios of solutes and ionic mobile phase components using indirect detection. The binding to the adsorbent, μBondapak Phenyl, has been expressed by ion-pair distribution constants and tested in the retention models by non-linear regression. All the ionic compounds followed adsorption models of the Langmuir type comprising two kinds of binding sites with widely different adsorption capacities and binding constants. The results indicate certain differences between the two sites regarding the binding of cationic and anionic components, respectively.
