Micellar electrokinetic chromatography of graphene and chemically modified graphenes with dodecylbenzenesulfonate.

Modeling The Capacity Factor of Analytes in Micellar Electrokinetic Chromatography Using Computational Descriptors

       A multiple linear regression model is proposed to calculate capacity factor of  analytes using structural features computed using HyperChem software. The  chemical descriptors of analytes were computed using HyperChem software and  regressed against the experimental capacity factors of analytes collected from the  literature. The absolute average percentage deviation (AARD) and individua...

Separation of 1,4-benzodiazepine Derivates by Cyclodextrin Modified Micellar Electrokinetic Chromatography

The electrophoretic separation of electrically neutral benzodiazepines (BZDs) can be achieved by micellar electrokinetic chromatograpy (MEKC). The cyclodextrin (CD)-modified micellar electrokinetic chromatography separation of eight of the most frequently used BZD was obtained within 15 minutes at + 25 kV on a 64.5 cm x 50 μm I.D. silica capillary at 25C, using a 25 mM sodium tetraborate-50 mM ...

Enantiomeric separation of primaquine, an anti-malarial drug, by cyclodextrin-modified micellar electrokinetic capillary chromatography.

Analysis 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...

Qualitative Determination of Proanthocyanidin Cleavage Products After Acid-Catalyzed Degradation in the Presence of Excess Phloroglucinol by Cyclodextrin-Modified Micellar Electrokinetic Chromatography

A micellar electrokinetic chromatographic (MEKC) method has been established for the identification and determination of acid-catalyzed proanthocyanidin cleavage products in the presence of phloroglucinol. Using fused-silica capillaries (50=57 cm, 22 kV) with phosphate buffer containing sodium dodecyl sulfate as the surfactant and b-cyclodextrin as modifier, structurally similar phloroglucinol ...
