Determination of benzodiazepines by micellar electrokinetic chromatography

ELECTROPHORESIS, 1994
AbstractA 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.

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.

Profiling of cocaine by micellar electrokinetic chromatography.

Journal of capillary electrophoresis, 1998
The potential of micellar electrokinetic chromatography (MEKC) for the profiling of cocaine samples is described. An MEKC system containing sodium dodecyl sulfate (SDS) and methanol was optimized using a test mixture of cocaine, its common impurities (benzoylecgonine, norcocaine, tropacocaine, and trans-cinnamoylcocaine), and several degradation ...

Determination of sunscreen agents by micellar electrokinetic chromatography

Journal of Pharmaceutical and Biomedical Analysis, 1995
The separation of UV-A and UV-B sunscreens by micellar electrokinetic chromatography has been studied. The optimized method, which involves the presence of an anionic surfactant (sodium dodecyl sulphate) and an organic modifier in the background electrolyte, was applied to determine these sunscreens in cosmetic products. Identification was achieved by "

Comparison of micellar electrokinetic chromatography and microemulsion electrokinetic chromatography for separation of pharmacologically active xanthones fromSecuridaca inappendiculata

Journal of Separation Science, 2003
Micellar electrokinetic chromatography (MEKC) and microemulsion electrokinetic chromatography (MEEKC) have been investigated for the separation of nine xanthones from Securidaca inappendiculata, based on the systematic optimization of such parameters as ...

Micellar electrokinetic chromatography on microchips

Journal of Separation Science, 2008
AbstractThis 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.

Micellar Electrokinetic Chromatography

2018
Micellar 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

2008
The 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.
