Abstract
The effect of selectivity-influencing parameters in ion-interaction chromatography is investigated by separating positionally isomeric decane monosulfonates. The authors find pronounced contributions to selectivity by the compact phase and the organic solvent in the fluid phase. Further, it is shown that the type and concentration of the ion-interaction reagent are particularly significant. The required separations could only be achieved by taking into account all terms of the resolution equation. The experiments resulted in the development of a chromatographic system by which positionally isomeric alkane monosulfonates up to C18 can be separated. They are of general interest in reversed-phase ion-interaction chromatography with indirect photometric detection.Keywords
