Abstract

A retention equation of general validity is adapted to ion exchange chromatography providing a self-consistent interpretation of retention of solutes and system peaks. Discussion is limited to eluent mixtures containing ions of invariant charge and to stationary phases with pH-independent surface charge. An interpretation is proposed for the retention volume of system peaks in binary eluents (mixtures of two eluent counter-ions). Retention volumes of labelled counter-ions of the eluent appear to provide useful information about the chromatographic system with clear interpretation in any multicomponent eluent.
