Resolution optimization was investigated by varying type, concentration and pH of buffers. Using the pH 9.2 buffer containing 30 mM Na2B4O7, 90 mM NaH2PO4and 0.5 mM tetradecyltrimethyl ammonium bromide, baseline resolution (Rs> 1.5) was found for all analytes. Advantages of the developed CZE method include simple sample preparation, fast analysis time within 5 min and high accuracy and precision. © 2007 Elsevier B.V.
