Optimization strategies in micellar electrokinetic capillary chromatography
Chromatographia, 1995Computer-assisted procedures for the one-parameter optimization of the surfactant concentration and the concentration of urea or D-glucose as modifiers in micellar electrokinetic capillary chromatography have been developed. These procedures permit a rapid optimization of one parameter on the basis of only two experiments. Predicted values are compared

Analysis of water-soluble vitamins by micellar electrokinetic capillary chromatography
Journal of Chromatography A, 1988Seven water-soluble vitamins were determined simultaneously by micellar electrokinetic capillary chromatography with UV detection. All these compounds were separated from each other within ca. 22 min by using a carrier containing sodium dodecyl sulphate as the surfactant. On-column detection at 254 nm with ethyl p-aminobenzoate as the internal standard

Analytical and Bioanalytical Chemistry, 2004
A fast and simple micellar electrokinetic capillary chromatographic method was developed for the analysis of piribedil in pharmaceutical formulations. The effects of buffer concentration, buffer pH, sodium dodecyl sulphate (SDS) concentration, organic modifier, applied voltage and injection time were investigated.

Determination of antitubercular drugs by micellar electrokinetic capillary chromatography (MEKC)
Analytical and Bioanalytical Chemistry, 2002A method for the determination of isoniazid (ISO), pyrazinamide (PYR) and rifampicin (RIF) in pharmaceutical products, by micellar electrokinetic capillary chromatography (MEKC) with ultraviolet detection is described. The influence of pH, concentration of surfactants, buffer and organic solvents, over the separation were studied as experimental ...

Adjusting selectivity in micellar electrokinetic capillary chromatography with 1,2-hexanediol
Electrophoresis, 1999In this report, we introduce a new micelle modifier useful to alter selectivity in micellar electrokinetic capillary chromatography (MECC). 1,2-Hexanediol acts as a class I organic modifier in that its effects are on the sodium dodecyl sulfate (SDS) micellar rather than the surrounding aqueous phase. This characteristic allows 1,2-hexanediol to improve

ELECTROPHORESIS, 2006
AbstractThe ability to separate nitroaromatic and nitramine explosives in seawater sample matrices is demonstrated using both MEKC and CEC. While several capillary‐based separations exist for explosives, none address direct sampling from seawater, a sample matrix of particular interest in the detection of undersea mines.

Serum antipyrine concentrations determined by micellar electrokinetic capillary chromatography
Journal of Chromatography B: Biomedical Sciences and Applications, 1993We developed an assay for antipyrine in serum using micellar electrokinetic capillary chromatography. A capillary electrophoresis system with a 70-cm fused-silica capillary and pH 8.2 borate-sodium dodecyl sulfate buffer was used. Standard curves ranging from 0.5 microgram/ml to 25 micrograms/ml were analyzed.
