Ionic liquids in the form of organic salts are being widely used as new solvent media. Here we investigate the chromatographic behavior, with reversed –phase high performance liquid chromatography (RP-HPLC), of 10 compounds on a C18 column in several different mobile phase additives, including 1-Hexyl-3-methylimidazolium tetrafluoroborate ([HMim][BF4]) and 1-Octyl-3-methylimidazolium tetrafluoroborate ([OMim][BF4]). The effect of the imidazolium ring, and the ionic liquid’s counterions on retention and resolution of the samples were tested. The results show the potential application of a used buffer system, ion pairing system, and ionic liquid as mobile phase additives in liquid chromatography. |
