| 英文摘要 | a packed-bed electroosmotic pump (eop) was constructed and evaluated. the eop consisted of three capillary columns packed in parallel, a gas-releasing device, pt electrodes and a high-voltage power supply. the eop could generate output pressure above 5.0 mpa and constant flow rate in the range of nl/min to a few mul/min for pure water, pure methanol, 2 mm potassium dihydrogenphosphate buffer, the buffer-methanol mixture and the pure water-methanol mixture at applied potentials less than 20 w the composition of solvent before/after pumping was quantitatively determined by using a gas chromatograph equipped with both flame ionization detector and thermal conductivity detector. it was found that there were no apparent changes in composition and relative concentrations after pumping process for a methanol-ethanol-acetonitrile mixture and a methanol-water mixture. theoretical aspect of the eop was discussed in detail. an capillary hplc system consisting of the eop, an injection valve, a 15 cm x 320 mum i.d., 5 mum spherigel c(18) stainless steel analytical column, and an on-column uv detector was connected to evaluate the performance of the eop. a comparative study was also carried out with a mechanical capillary hplc pump on the same system. the results demonstrated that the reproducibility of flow rate and the pulsation-free flow property of the eop are superior to that of mechanical pump in capillary hplc application.
