The results of ion-pair chromatography with UV-absorbing counterions are described. Hydroxynaphthalenesulfonic acids are used as ion pair formers, and alkaloids as test samples. The separations are performed on silanized silica gel from Merck and KC18F plates from Whatman. The influence of the counterion on the Rf-value is demonstrated. Some alkaloids exhibit characteristic fluorescence as ion pairs.
