Abstract
An apparatus for separating particles within a medium which is capable of generating electric fields having adjustable magnitudes and orientations is disclosed herein. The electrophoretic apparatus of the present invention includes electrode arrangement for providing a plurality of sets of opposing individually responsive electrodes for generating electric fields within the medium, each field having at least one magnitude and direction. The invention further includes a control circuit for selectively controlling electrodes within the electrode sets to vary the magnitudes and directions of the electric fields at locations within the medium. The electric fields induce differing rates of motion of the particles thereby separating the particles.
