This paper reviews and discusses the analytical combination of ionic liquids (IL) with CE.
On the one hand, it shows CE as a powerful technique to separate impurities from IL as well
as being capable to determine physical and chemical properties of IL. On the other hand, it
also shows how IL are employed in CE separations to enhance resolution, peak efficiency
and peak symmetry. Specifically, IL are used as additives in CZE, NACE, and MEKC and as
support coatings of the capillary wall in electrochromatography. The integrity of the IL in
the electrophoretic system as well as the roles of the cations and anions of the IL in the
electrophoretic separation are also discussed.
