TLDR
In this paper, the authors reviewed the potential of room temperature ionic liquids as mobile phases or mobile phase additives in separation science and proposed a new class of solvents of potential interest for liquid chromatography.Abstract:
Room temperature ionic liquids are a new class of solvents of potential interest for liquid chromatography. Ionic liquids possess a combination of physical and solvation properties that are complementary to conventional organic solvents. Applications in liquid chromatography are currently limited by their unfavorable viscosity and low-wavelength absorption in the ultraviolet (UV) region. In addition, for planar chromatography, the absence of a vapor pressure does not allow evaporation of ionic liquid solvents after development. The room temperature ionic liquids are good solvents for nonionic compounds with a different blend of intermolecular interactions compared with conventional organic solvents as indicated by solvatochromic measurements and the system constants of the solvation parameter model. Current applications in column and planar chromatography are reviewed to demonstrate the potential of room temperature ionic liquids as mobile phases or mobile phase additives in separation science. A real breakthrough in their use, however, requires the identification of new room temperature ionic liquids with viscosity closer to those of conventional organic solvents as well as addressing other minor issues described in the text.read more

Solvent Selection for Liquid-Phase Extraction
TL;DR: The main solvent classification methods employ Hildebrand's solubility parameters, Snyder's solvent-selectivity triangle, solvatochromic parameters, Abraham's solvation parameter model, and the conductor-like screening model for real solvents (COSMO-RS).
