The separation challenges that keep arising from the constantly evolving practical applications encountered in ion‐pair chromatography (IPC) of inorganic analytes and inorganic elements The extraction of an ion pair to the organic phase was considered to be the cause of retention, and the name ion pair chromatography originates from this early application. When covalently bonded non-polar stationary phases were introduced, important contributions to the further development of IPC were, among others, made by the research groups of Horváth, Knox, Schill and Haney.

Ion Pair Chromatography is used . to separate . ionic analytes on a reversed phase column in HPLC. This chromatography is based on the . addition of ionic compounds (Ion Pair reagents) to the mobile phase to promote the formation of ion pairs with ionic analytes in the sample to modulate retention of ionic analytes themselves. In reversed-phase ion pair chromatography, the addition of an appropriate ion–pairing reagent (tetrabutylammonium hydrogensulfate) to the mobile phase suppresses the ionic nature of the sample while introducing some charge to the nonpolar surface of the stationary phase. The retention of the resulting ion pair is then controlled by pH, counterion concentration and mobile phase polarity

Ion Exchange chromatography Principle. The charged molecules in the sample are separated by the electrostatic forces of attraction when passed through the ionic resin at particular pH and temperature. The separation occurs by reversible exchange of ions between the ions present in the solution and those present in the ion exchange resin. This chapter describes the ion chromatography theory and applications in detail. At present, there are three main separation methods in ion chromatography, including Ion chromatography (IC), Ion exclusion chromatography (IEC), and Ion pair chromatography (IPC).
