Summary
Retention models for anionic analytes and mobile phase compounds in reversed-phase ion-pair chromatographic systems have been studied. The solid phase was a polystyrene-divinylbenzene copolymer. The analytes were mono- and divalent anions monitored by indirect detection technique. The mobile phase was highly alkaline and contained a detectable anion, sulfanilic acid.
Expressions for the ion-pair retention of solutes and mobile phase components have been developed assuming Langmuir distribution of ion-pairs to a solid phase with one kind of binding site. The validity of the expressions and the origin of system peaks have been confirmed by determination of distribution constants using linear regression.
