<p>The electrophoretic separator (10) comprises: an array of subcompartments (12) with two electrode compartments (30, 32) on either side of the array, each subcompartment has an inlet port (11) and a collection port (13); a buffer reservoir; a throughput pump (68) for supplying buffer from the buffer reservoir to each inlet port; a sample pump for supplying sample to the inlet port(s) of one or more subcompartments; a fraction pump (70) for withdrawing an even fractional portion of the fluid flow pumped out of each of the collection ports; and a centering withdrawal pump (80) for withdrawing an additional portion of the fluid flow out of one of exit ports adjacent to one of the electrode compartments. The fraction pump and centering withdrawal pump create a counterflow gradient in the subcompartments.</p> |
