“…A thermodynamic comparison of tetra-n-butyl-phosphonium and -ammonium ILs showed the phosphonium compounds solvate hydrocarbons better [35]. Enhanced weak dispersive forces and proton donor interactions for tetraalkyl ammonium perfluoroalkane sulfates as compared to their hydrocarbon GC stationary phase counterparts was a major conclusion [36,37]. Finally, the possibility of chemical reactions involving alkylammonium-based IL GC stationary phases which could be responsible for the retention of various organic solutes was considered [38].…”

Ionic liquids (ILs), as separation media, have made significant contributions in the past decades in advancing research in gas chromatography (GC), liquid chromatography (LC), and capillary electrophoresis (CE). This review, covering reports published from the mid 1980s to early 2007, shows how ILs have been used so far in separation science, originally primarily as GC stationary phases and later as mobile phase additives (both millimolar and major percent levels) for LC and CE. Representative GC and LC chromatograms as well as CE electropherograms are shown. In addition, the very recent findings on the development of ionic liquids with surfactant properties and its applications for chiral and achiral analysis are discussed.

Interest in ionic liquids with fluorine-containing cations has grown markedly in recent years. The syntheses, characterization and properties of quaternary fluoroalkyl-substituted ammonium, imidazolium, triazolium, pyridinium, pyrazinium, pyridazinium, pyrimidinium, piperazinium, pyrrolidinium, oxazolidinium, and morpholinium salts have been studied in detail. By modifying the anion or the fluorine-containing substituent on the cation, a wide range of properties of fluorine-containing ionic liquids can be tuned, including
