## 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.

β¦ Synopsis
This separation method is increasingly finding applications in environmental, food, pharmaceutical and clinical analysis.
The completely revised and updated fourth edition of this best-selling classic is a thorough treatment of the subject while remaining concise and readable. Alongside ion exchange resins, detectors, ion chromatographic separations, anion, cation and ion exclusive chromatography, special techniques and chemical speciation, new additions include capillary electrophoresis, monolithic columns, zwitterion columns, DNA/RNA analysis, fundamentals of the science of IC, and micro methods.
The whole is rounded off by handy tables with details on, among others, detection or elution conditions, making this a ready reference for analytical, environmental and food chemists, chromatographers, pharmaceutists, and chemists working in trace analysis.

13 Ion-Pair Chromatography ### 13.1 Introduction Ion-pair chromatography represents an alternative to ion-exchange chromatography. Many problems can be solved by either method but ion-exchange is not as good for separating mixtures of acids, bases and neutral products under certain circumstances,
## Abstract Catecholamine standards have been separated by ion pairing reversedβphase highβperformance liquid chromatography (HPLC). A trace substance was separable from four standards when low concentrations of methanol were used in the elution buffer. This method has allowed separation of an unkn
Paired ion high-pressure liquid chromatography was useful for separating intact catecholamines (epinephrine, isoproterenol, levodopa, and methyldopa) and phenylephrine from some of their decomposition products. Furthermore, methyldopa was separated from either hydrochlorothiazide of levodopa. Under
