The electroosmotic flow (or electro-osmotic flow, often abbreviated as EOF, synonymous with electroosmosis or electroendosmosis) is the movement of liquid induced by a potential applied through a porous material, capillary tube, membrane, microcanal or any other fluid conduit . Because the electroosmotic velocities are independent of the duct size, while the electric double layer is much smaller than the characteristic channel length scale, the electroosmotic flow will have little effect. Electroosmotic flow is most significant when it is found in small channels. Electroosmotic flow is an essential component in chemical separation techniques, in particular capillary electrophoresis. Electroosmotic flow can occur in unfiltered natural water as well as buffered solutions.
The electroosmotic flow was first reported in 1809 by F. F. Reuss in the Proceedings of the Imperial Society of Naturalists of Moscow. He showed that water could be made to flow through a plug of clay by applying an electric voltage. The clay is composed of silica particles and other tightly packed minerals, and water flows through the narrow spaces between these particles, just as it would through a narrow glass tube. Any combination of an electrolyte (a fluid containing dissolved ions) and an insulating solid would generate electro-osmotic flow, although for water / silica the effect is particularly large. Even so, flow rates are typically only a few millimeters per second.
