摘要：

The flow profile of electroosmosis in capillary electrophoresis was studied by using a dye and a rectangular capillary. The movement of the dye is observed with a microscope-video system, and then advances per unit time are measured from the recorded video tapes. The medium at the central portion moves like a plug flow, and the zone front at the edges are ahead of the central portion. The flow profile in a capillary column with a circular cross-section is proposed. The flow profiles of ionic solutes are also discussed.
