## Abstract The results of investigations with ion pair chromatography on RP~2~, RP~8~ and RP~18~ thin layers are described. Heptane sulphonic acid is used as ion pair former. The best results are achieved on RP~18~βlayers with the counter ion in the mobile phase.
Some possibilities are described to improve the separation between catecholamines and their corresponding metanephrines in reversed-phase ion-pair partition chromatography. The retention of amines can be influenced by the perchlorate concentration of the mobile phase, while the retention of acidic m
