Abstract:
1. An electrophoresis apparatus for separating particles in a flowing liquid sample, comprising: a microchip; a chamber in said microchip, said chamber having a first chamber wall and a second chamber wall wherein said flowing liquid sample is between said first chamber wall and said second chamber wall; a first reservoir containing a first conductive liquid; a first metal electrode in said first reservoir in contact with said first conductive Liquid; a first pump connected to said first reservoir for pumping said first conductive Liquid; a first flowing conductive liquid electrode within said chamber connected to said first conductive liquid and said first pump wherein said first flowing conductive liquid electrode is positioned along said first chamber wall and positioned wherein the flowing liquid sample is in direct contact with said first flowing conductive liquid electrode; a second reservoir containing a second conductive liquid; a second metal electrode in said second reservoir in contact with said second conductive liquid; a second pump connected to said second reservoir for pumping said second conductive liquid; a second flowing conductive liquid electrode within said chamber connected to said second conductive liquid and said second pump wherein aid second flowing conductive liquid electrode is positioned along said second chamber wall opposite first chamber wall and positioned wherein the flowing liquid sample is in direct contact with said second flowing conductive liquid electrode; and an electric field generated from associated circuitry applied to said first flowing conductive liquid electrode and said second flowing conductive liquid electrode.
