A micellar electrokinetic capillary chromatographic method for the separation of tetrahydroberberine alkaloids was established. An electrolyte solution of 0.02 M sodium dodecyl sulphate (SDS) in 0.03 M borate buffer (pH 9) containing 10% acetonitrile, and an applied voltage of 20 kV, were found to b

The enantiomeric separation of atropisomeric polychlorinated biphenyls ลฝ was studied by cyclodextrin-modified micellar electrokinetic chromatography CD-. MEKC . Four CD derivatives were investigated as chiral selectors, and 2-hydroxyl-โฅ-CD gave the best resolution for the separation of PCB 84. Three
A simple mathematical model describing the separation of a series of aromatic bases by electrokinetic chromatography using beta-cyclodextrin (beta-CD) as a pseudostationary phase is described. The model takes into account changes in electrolyte pH and the different formation constants between the ne
