| Abstract: | An open-tubular capillary column bonded with γ-aminopropyltriethoxysilane was prepared. By this column,8 neutral aromatic hydrocarbons were separated efficiently by the electrophoresis in ammonia/methanol (30∶70, V/V) solvent as separation medium. The resolution was studied under various electrophoresis conditions, such as voltage, concentration of sodium dodecyl sulfate (SDS) and ammonia. Result shows that the 8 neutral aromatic hydrocarbons got the effective separation and good reproducibility on the column. |
