The control of electroosmotic flow by electronic means for capillary zone electrophoresis is presented. This is accomplished by the application of a radial voltage field with a rugged and flexible conductive polymer sheath. Fundamental theory for effect of the applied radial voltage on electroosmotic flow is developed. In addition, the effects of surface pretreatments are examined and compared to trends predicted by the theory.
