摘要：

High efficiency Capillary Electrophoresis (CE) separation (440 - 760 thousand theoretical plates per meter) of metal-edta complexes and inorganic anions has been demonstrated using Kinetic Differentiation mode - Ion-Exchange Electrokinetic Chromatography (EKC). An aromatic homolog of polyamino-carboxylate (Quin 2, see Figure 1) has been used for the increase of the detection sensitivity. The detection limits of transition metals were found in the range of (0.59 -1.90) x 10(-6) M (M = mol dm(-3)).
