Twenty-five years of micellar electrokinetic chromatography
Micellar electrokinetic chromatography (MEKC), which can separate neutral analytes as well as charged analytes by the capillary electrophoretic technique, was developed in 1982 and the first paper was published in 1984. The authors’ group concentrated their effort into the characterization of MEKC as a separation technique until early 1990s. Most issues in MEKC separations were successfully sol...
متن کاملPoly(dimethylsiloxane) microchip for precolumn reaction and micellar electrokinetic chromatography of biogenic amines.
We have demonstrated that precolumn derivatization and capillary electrophoresis separation on a poly(dimethylsiloxane) (PDMS) microchip can be realized as efficient as those on glass microchips. In an optimized condition of micellar electrokinetic chromatography (MEKC), using 25 mM sodium borate buffer (pH 10.0) with 25 mM sodium dodecyl sulfate (SDS) and 5% v/v methanol, the electroosmotic fl...
متن کاملDetermination of aminoglycoside antibiotics in pharmaceuticals by capillary zone electrophoresis with indirect UV detection coupled with micellar electrokinetic capillary chromatography.
Aminoglycoside antibiotics can be determined by capillary zone electrophoresis (CZE) with indirect UV detection in the anionic mode with a reversed electroosmotic flow (EOF) by addition of FC 135 to the background electrolyte. The effective mobilities of thirteen aminoglycoside antibiotics were determined as a function of pH. Applying CZE with indirect UV detection in the anionic mode and rever...
متن کاملAnalysis of prostaglandins by micellar electrokinetic capillary chromatography.
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. Moreover, the influences of electrolyte concentration and capillary temperature...
متن کاملPrinciples of micellar electrokinetic capillary chromatography applied in pharmaceutical analysis.
Since its introduction capillary electrophoresis has shown great potential in areas where electrophoretic techniques have rarely been used before, including here the analysis of pharmaceutical substances. The large majority of pharmaceutical substances are neutral from electrophoretic point of view, consequently separations by the classic capillary zone electrophoresis; where separation is base...
