“…The introduction of ion chromatography (IC) by Small et al ( 1) has proved high-performance liquid chromatography (HPLC) to be a useful tool for ionic analysis. Separation modes used for IC involve ion-exchange (1)(2)(3)(4), ion-exclusion (5), or ion-interaction chromatography (IIC, also called ion-pair chromatography) (6)(7)(8)(9)(10)(11). The latter is recognized basically as a type of ion-exchange chromatography, because ion-pairing reagents adsorbed on a nonpolar stationary phase behave as ion-exchange sites.…”

“…Advantages of IIC include the use of conventional HPLC equipment for ionic analysis and the ability to tailor the ion-exchange capacity for the particular application (10,11). Thus, ionic separation on nonpolar stationary phases, has been investigated by using cationic ion-interaction reagents, e.g., hexadecyltrimethylammonium (HTA) salts, tetraalkylammonium salts, and 1,10-phenanthroline chelates for anion analysis (7)(8)(9)(10)(11) and anionic ion-interaction agents, e.g., sodium dodecyl sulfate, for cation analysis (11).…”

“…A third approach that is versatile in scope is to use a detector active ion interaction (II) reagent (ion pairing reagent) as a mobile phase additive. Most studies have focused on an additive and/or its counterion that is chromophoric (8)(9)(10)(11)(12)(13). In addition to its involvement in ID the II additive is also responsible for the separation (11,13).…”

“…We have recently shown that iron(II) 1,10-phenanthioline salts are excellent II reagents for the separation and indirect photometric detection (IPD) of inorganic and organic analyte anions (11)(12)(13). The studies discussed here focus on the use of highly fluorescent ruthenium(II) 1,10-phenanthroline, Ru(phen)32+, and ruthenium(II) 2,2'-bipyridine, Ru(bpy)32+, salts as mobile phase II reagents for the separation and IFD of inorganic and organic analyte anions.…”

Ion chromatography (IC), which is an important methodology within high‐performance liquid chromatography (HPLC), is a chromatographic separation/detection strategy that is applied to the determination of inorganic and organic analyte anions and cations. The methodology consists of three main components: (1) a low‐capacity ion‐exchange column, where the separation occurs; (2) a suppressor system, which reduces conductivity due to the mobile phase electrolyte; and (3) a conductivity detector, which is used to detect the analyte ions. Anionic analytes are separated on an anion‐exchange column and analyte cations are separated on a cation‐exchange column. IC, which is routinely applied in water, environmental, health, and food analysis, is a rapid, sensitive, and accurate method for the trace determination of complex mixtures of analyte ions, particularly analyte anions, where no other method offers similar advantages and scope of application. Today, the term IC defines a broader group of methodologies applicable to the separation of analyte ions and now also defines the following strategies. Nonsuppressed IC of analyte anions and cations is possible. In addition, analyte ions can be separated with an ion interaction reagent (ion pair reagent) as a mobile phase additive and a reversed stationary phase column rather than an ion‐exchange column; this is often called ion interaction chromatography (IIC). Ion exclusion chromatography (IEC), which is a separation of weakly dissociated acid and base analytes on an anion exchanger, is also an important methodology within the field of IC.
