Electrochromatography MEKC

CE was recently used for anthocyanin analysis because of its excellent resolution. This technique has different modes capillary zone electrophoresis (CZE), capillary gel electrophoresis (CGE), micellar electrokinetic chromatography (MEKC), capillary electrochromatography (CEC), capillary isoelectric focusing (CIEE), and capillary isotachophoresis (CITP)."° CZE is the most popular method for anthocyanin... [Pg.489]

CE is a family of techniques similar to those found in conventional electrophoresis zone electrophoresis, displacement electrophoresis, isoelectric focusing (IEF), and sieving separations. Other modes of operation unique to CE include micellar electrokinetic chromatography (MEKC) and capillary electrochromatography (CEC). [Pg.164]

Dedicated applications of capillary zone electrophoresis (CZE) coupled to MS are discussed, particularly in the field of drug analysis. Development of other capillary-based electrodriven separation techniques such as non-aqueous capillary electrophoresis (NACE), micellar electrokinetic chromatography (MEKC), and capillary electrochromatography (CEC) hyphenated with MS are also treated. The successful coupling of these electromigration schemes with MS detection provides an efficient and sensitive analytical tool for the separation, quantitation, and identification of numerous pharmaceutical, biological, therapeutic, and environmental compounds. [Pg.478]

The majority of enantioseparations are performed by pressure-driven liquid chromatography. However, in the last decade other liquid-phase separation techniques have evolved and demonstrated their usefulness for enantioseparations, including supercritical fluid chromatography (SFC), capillary electrophoresis (CE), micellar electrokinetic chromatography (MEKC), and open-tubular and packed-bed electrochromatography (OT-EC and CEC). [Pg.433]

Microextractions have the capability to concentrate selectively compounds with particular chemical properties, and to reject solutes with other particular chemical properties. Microextractions function on a small volume scale. As the volumes involved in microextraction and CE can be (but are not necessarily) the same, and given the capability of microextraction to concentrate analytes selectively, microextractions are a natural choice for improving virtually any CE (micellar electrokinetic chromatography, MEKC capillary electrochromatography, CEC etc.) method. [Pg.812]
