A micellar electrokinetic capillary chromatographic method for the separation of anthraquinone positional isomers was established. The running electrolytes used in this method were 0.03 M sodium dodecyl sulphate (SDS) in 0.03 M borate buffer (pH 9) containing 10% acetonitrile for dihydroxy-and dihyd
We developed a micellar electrokinetic chromatography method (MEKC) for the direct determination of the content of synthesized alpha-vitamin E. It was found that under the optimum separation conditions 7 mM borate + 14 mM phosphate + 15 mM sodium dodecyl sulfate (SDS) + 10 mM sodium cholate (NaCh) +
