英文摘要 | a polymer-based neutral monolithic capillary column was prepared by radical polymerization of glycidyl methacrylate and ethylene dimethacrylate in a 100 lam id fused-silica capillary, and the prepared monolithic column was subsequently modified based on a ring opening reaction of epoxide groups with 1 m lysine in solution (ph 8.0) at 75 degrees c for 10 h to produce a lysine chemically bonded stationary phases in capillary column. the ring opening reaction conditions were optimized so that the column could generate substantial eof due to the zwitterionic functional groups of the lysine covalently bonded on the polymer monolithic rod, the prepared column can generate cathodic and anodic eof by varying the ph values of running buffer during cec separation. eof reached the maximum of -2.0 x 10(-8) m(2)v(-1)s(-1) and 2.6 x 10(-8) m(2)v(-1)s(-1) with ph of the running buffer of 2.25 and 10, respectively. as a consequence, neutral compounds, ionic solutes such as phenols, aromatic acids, anilines, and basic pharmaceuticals were all successfully separated on the column by cec. hydrophobic interaction is responsible for separation of neutral analytes. in addition, the electrostatic and hydrophobic interaction and the electrophoretic migration play a significant role in separation of the ionic or ionizable analytes. |
