SWEEPING FLOW ELECTROPHORESIS (SFE): A NEW CONTINUOUS SEPARATION TECHNIQUE

In this paper, a new principle for continuous electrophoretic separation is introduced. An electrokinetically pinched sample flow is swept through a microfluidic chamber. The wavelengths of the resulting sine-waves are in direct relation with the electrophoretic mobility of the compound. The principle is applied to separate Rhodamine B and Fluorescein.
