Analyte–additive interactions in nonaqueous capillary electrophoresis: a critical review

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 cha...

Description
Summary: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.
