- Abstract−Ionic liquids (ILs) have gained wide recognition as novel solvents in chemistry. Their application in analytical
chemistry, especially in separating analytes, is warranted due to their unique properties such as negligible vapor pressure,
good thermal stability, tunable viscosity and miscibility with water and organic solvents, as well as good extractability
for various organic compounds and metal ions. Recently, some new chromatographic separation media, formed by
combining ILs on silica and polymer surface using covalently or non-covalently interaction, have been developed and
applied to biological separation and environment analysis. This review will focus on some of the properties of ILs and
their potential application as mobile phase modifier and surface-bonded stationary phase in high-performance liquid
chromatography (HPLC) separation.
