英文摘要: An electroosmotic pump (EOP) capable of generating pressure above 3 MPa and mul/min flow rate with reverse phase mobile phases of HPLC was constructed and evaluated. The pump consisted of three parallel connected fused silica capillary columns (25 cm x 320 mum I.D.) packed with 2 mum silica materials, hollow electrodes, a high voltage DC power supply, and. a liquid pressure transducer. The EOP was applied in a capillary liquid chromatographic system for mobile phase delivery instead of a mechanical pump. Standard samples containing thiourea, naphthalene, anthracene, phenanthrene and acetonitrile were separated on a 15 cm x 320 mum I.D. 5 mum Chromasil C-18 packed capillary column with acetonitrile/water as mobile phase.
