Micellar Electrokinetic Chromatography
Bulletin of the Chemical Society of Japan, 1998Abstract A review of the research on micellar electrokinetic chromatography (MEKC), carried out mainly in our laboratory, is described from the viewpoints of (1) fundamental characteristics of MEKC, such as the separation principle, chromatographic parameters, selectivity and resolution, thermodynamic parameters, retention index, and ...

Micellar electrokinetic chromatography on microchips
Journal of Separation Science, 2008AbstractThis review highlights the methodological and instrumental developments in microchip micellar EKC (MCMEKC) from 1995. The combination of higher separation efficiencies in micellar EKC (MEKC) with high‐speed separation in microchip electrophoresis (MCE) should provide high‐throughput and high‐performance analytical systems.

Determination of benzodiazepines by micellar electrokinetic chromatography
ELECTROPHORESIS, 1994AbstractA method for the separation and determination of benzodiazepines by micellar electrokinetic chromatography (MEKC) has been developed. Separation buffers consisted of aqueous solutions of glycine and triethanolamine (pH 9.0), containing sodium dodecyl sulfate (SDS) as surfactant and methanol as organic modifier.

Micellar Electrokinetic Chromatography
2018Micellar electrokinetic chromatography (MEKC) is a mode of capillary electrophoresis that allows for the separation of neutral molecules in an electric field. Typically, neutral molecules move with electroosmotic flow (EOF) or bulk flow during electrophoretic separations resulting in no temporal resolution between mixtures of neutral analytes ...

Micellar Electrokinetic Chromatography of Aminoglycosides
2008The components of the aminoglycosides, e.g., gentamicin, sisomicin, netilmicin, kanamycin, amikacin, and tobramycin, and related impurities of these antibiotics can be separated by means of micellar electrokinetic chromatography (MEKC). Derivatization with o-phthaldialdehyde and thioglycolic acid is found to be appropriate for all antibiotics.

Microemulsion and micellar electrokinetic chromatography of steroids
Journal of Chromatography B: Biomedical Sciences and Applications, 1996A mixture of ten steroids was separated by microemulsion and micellar (SDS and glycodeoxycholate) electrokinetic chromatography systems. Separations were done on a 50 cm (to the detector) x 50 microns I.D. fused-silica capillary. Complete separation of all the test compounds in the micellar mode was obtained with glycodeoxycholate (50 mM) in 25 mM ...

Determination of nikethamide by micellar electrokinetic chromatography
Biomedical Chromatography, 2019AbstractA simple, fast, sensitive and reproducible micellar electrokinetic chromatography (MEKC)–UV method for the determination of nikethamide (NKD) in human urine and pharmaceutical formulation has been developed and validated. The method exhibits high trueness, good precision, short analysis time and low reagent consumption.

Microemulsion electrokinetic chromatography: comparison with micellar electrokinetic chromatography
Journal of Chromatography A, 1992Abstract The fundamental characteristics of microemulsion electrokinetic chromatography (MEEKC) were studied in comparison with micellar electrokinetic chromatography (MEKC). A microemulsion consisting of heptane-sodium dodecyl sulphate-butanol-buffer (pH 7.0) (0.81:1.66:6.61:90.92) was mainly employed.

Micellar Electrokinetic Chromatography
2013Since the introduction of micellar electrokinetic chromatography by Terabe, several authors have paid attention to the fundamental characteristics of this separation method. In this chapter the theoretical and practical aspects of resolution optimization, as well as the effect of different separation parameters on the migration behavior are discussed ...

Micellar electrokinetic chromatography-mass spectrometry
Journal of Chromatography A, 1997The combination of micellar electrokinetic chromatography (MEKC) with mass spectrometry (MS) is very attractive for the direct identification of analyte molecules, for the possibility of selectivity enhancement, and for the structure confirmation and analysis in a MS-MS mode.
