In this work the suitability of micellar electrokinetic capillary chromatography (MEKC) and nonaqueous capillary electrophoresis (CE) to the analysis of the primary oxidation products of linoleic acid was studied with uncoated fused-silica capillaries. The primary autoxidation products of linoleic a
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
