Abstract
A cyclic capillary electrophoresis device includes a capillary channel that forms a closed loop. The capillary channel comprises an inner half facing toward a space enclosed by the loop, where the inner half having an inner wall of first charge density, and an outer half facing away from the space enclosed by the loop, where the outer half having an inner wall surface of second charge density. A difference between the first and the second charge densities exists or can be turned on. The difference is configured to create a smaller average electroosmotic flow velocity in the inner half than in the outer half.
