英文摘要: Reversed phase capillary electrochromatography (RP-CEC) was used to achieve the rapid analysis of six polycyclic aromatic hydrocarbons (PAHs). Capillary column packed with 5 mum ODS stationary phase in the 10 cm packed length (31 cm total length) and UV detector was used. The effect of the separation voltage, organic modifier on the electroosmotic flow (EOF) and column performance was investigated. Baseline separation could be reached in the 90% acetonitrile content and 10kV-separation voltage, and theoretical plate numbers per meter for six PAHs were all above 70,000. The total analytical time was less than 4 min with RSD less than or equal to 0.60% (in retention factor) and 9.83% (in peak area) under the optimized experimental conditions. When the solute strength of the sample solution was less than the elution strength of the mobile phase, on-column concentration of the analytes could be occurred.
