Since their initial discovery in 1914, ionic liquids (ILs) have been widely studied in multiple chemistry disciplines. Applications of ILs in analytical chemistry have enjoyed much success and contributed to the rapid evolution of the ionic liquid field. ILs are collectively known as organic salts which possess melting points at or below 100 °C. In most cases, ILs are composed of an organic cation and an organic or inorganic anion. It has been estimated there can be up to 1018 possible combinations of ILs, due to the ability to interchange their corresponding cationic/anionic moieties.

Chromatographic retention factors were measured for 45 different organic solutes of varying polarity and hydrogen-bonding capability on an anhydrous 1-(2-methoxyethyl)-1-methylpyrrolidinium tris(pentafluoroethyl)trifluorophosphate, ([MeoeMPyrr]+ [FAP]– ), stationary phase at both 323 K and 353 K. The experimental retention factor data were combined with recently published thermodynamic data for solutes dissolved in ([MeoeMPyrr]+ [FAP]– ) to give the corresponding gas-to-liquid partition coefficients (log K). The water-to-anhydrous ([MeoeMPyrr]+ [FAP]– ) partition coefficients (log P) were also calculated using published gas-to-water partition coefficient data for the solutes studied. The derived partition coefficients were analyzed in accordance with the Abraham model. The Abraham model expressions that …
