چکیده

The separation of nine furanonaphthoquinones by micellar electrokinetic chromatography (MEKC) is described. The running electrolytes used in this method were 0.03 M sodium dodecyl sulphate (SDS) in 0.09 M borate buffer (pH 9) containing 10% methanol, with an applied voltage of 20 kV. Application of this technique in the determination of the main furanonaphthoquinones, 5-hydroxy-2-(1-hydroxyethyl)naphtho[2,3-b]furan-4,9-dione, 8-hydroxy-2-(1-hydroxyethyl)naphtho[2,3-b]furan-4,9-dione, and 2-(1-hydroxyethyl)naphtho[2,3-b]furan-4,9-dione, of Tabebuia impetiginosa is demonstrated in this paper.

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...

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 ...

Micellar electrokinetic chromatography and capillary electrochromatography of nitroaromatic explosives in seawater.

The 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. Direct comparisons are made between MEKC and CEC in terms of sensitivity and separ...

The applicability of micellar electrokinetic capillary chromatography (MEKC) for the separation of benzodiazepine (BZD) derivates with different structural characteristics has been studied. Efforts were first focused on the optimization of the analytical conditions, on the effects of buffer concentration, surfactant concentration and buffer pH on the separation. To manipulate selectivity of the...
