摘要：

This article reviews the recent developments in nonaqueous capillary electrophoresis and discusses the effect of the solvent on analyte-additive interactions. When nonaqueous solvents are used, solvophobic interactions are generally weaker than those in water; therefore, those additives that can change the analyte mobility through electrostatic or donor-acceptor interactions should be further explored.
