The effect of the ligand concentration and of the mobile phase pH on the retention of analytes was studied in the first place. Relations were established between the capacity factor of the analytes and the ligand concentration in the mobile phase on the assumption that the retention is governed by an ion-exchange mechanism. It was found that in most cases the reciprocal value of the capacity factor is a linear function of the ligand concentration (at constant concentration of the eluting cation), which is consistent with the derived relations.
