Capillary Separation: Micellar Electrokinetic Chromatography

Annual Review of Analytical Chemistry, 2009
Micellar electrokinetic chromatography (MEKC), a separation mode of capillary electrophoresis (CE), has enabled the separation of electrically neutral analytes. MEKC can be performed by adding an ionic micelle to the running solution of CE without modifying the instrument.

Separation of reduced and oxidized glutathione by micellar electrokinetic capillary chromatography

Biomedical Chromatography, 1993
AbstractThe separation of reduced and oxidized glutathione at an absolute sensitivity of about 100 pg by micellar electrokinetic capillary chromatography without derivatization is described. The time required for the separation is less than 10 min (the time between two following injections is about 15 min).

Applications of in-capillary reaction micellar electrokinetic chromatography in the food industry

Journal of Chromatography A, 2000
This review describes the quantitative analysis of in-capillary reactions by using capillary electrophoresis (CE) in the food industry. An electrophoretic analysis of products of an enzyme reaction of a substrate by in-capillary reaction was useful for the activity measurement of glucoamylase in sake rice koji.

Micellar Electrokinetic Capillary Chromatography of Proteins

Analytical Biochemistry, 1993
Separations of model proteins obtained under denaturing conditions in the presence of micellar concentrations of ionic surfactants displayed high resolution and efficiency using either bare silica or C18-derivatized silica capillaries. Superior migration time reproducibility was achieved through the use of the C18-derivatized capillaries (run-to-run ...

Separation of fungicides by micellar electrokinetic capillary chromatography

ELECTROPHORESIS, 1997
AbstractCapillary electrophoresis with ultraviolet detection (CE/UV) of selected fungicides (carbendazim, metalaxyl, propiconazole, and vinclozolin) using different buffer compositions was investigated. Capillary zone electrophoresis (CZE) with 10 mM sodium phosphate (pH 7.0) was not useful in separating the four fungicides used in this study. However,

Analysis of prostaglandins by micellar electrokinetic capillary chromatography

Journal of Chromatography A, 1997
This paper presents a rapid and reliable micellar electrokinetic capillary chromatography (MEKC) method to separate major prostaglandins and thromboxane B2. The running buffer was modified with sodium dodecyl sulfate (SDS). The effects of the SDS concentration on the migration behavior of analytes was also examined.
