用电流监测法研究了外加电场对毛细管电泳中电渗方向和流速的影响。 利用所提出的电容器模型，对影响电渗直接控制的因素如溶液条件和毛细管尺寸进行了详细的测量和分析。 电容器模型预测合理以及在不同的溶液pH值，电解质浓度，和毛细管尺寸的实验结果的趋势。
The change in the direction and flow rate of electroosmosis in capillary electrophoresis with the application of an external electric field has been demonstrated and measured by the current-monitoring method. Factors such as solution condition and capillary dimension affecting the direct control of electroosmosis have been measured and analyzed in detail with the proposed capacitor model. The capacitor model predicted reasonably well the trends of experimental results at various solution pHs, electrolyte concentrations, and capillary dimensions.
