Apparatus and process for controlling the rate of electroosmosis due to a first electric potential in an electrically insulating capillary, in which a second electric potential is applied between the electrically insulating walls of the capillary and a liquid within the capillary. This second electric potential changes the charge on the wall of the capillary, and thus allows manipulation of the zeta potential within the capillary, and therefore the rate of electroosmosis.
