      Liquid chromatography with room temperature ionic liquids
      N. LENCA, C. POOLE* (*Department of Chemistry, Wayne State University,
      Detroit, MI 48202, USA, cfp@chem.wayne.edu)

      J. Planar Chromatogr. 30, 97-105 (2017). Review of current applications of room temperature ionic liquids on planar chromatography as mobile phases. Methylammonium, ethylammonium, propylammonium, isopropylammonium, butylammonium, s-butylammonium, dipropylammonium, tributylammonium were reported to be used as replacements for organic solvents in binary systems. As mobile phase additives, room temperature ionic liquids were used for the separation of peptides and basic drugs in both normal phase and reversed phase chromatography with an emphasis on their role as masking agents. The authors suggested that given the large number of possible cation and anion combinations, systematic methods that characterize solvation properties for both ionic liquids and organic solvents are required.
