Patent ID: 7211184

Claim:
A capillary electrophoresis device, comprising: a device body structure having a first surface and a second surface, wherein a plurality of reservoirs are arrayed on said first surface and a plurality of grooves are transversely defined on said second surface; at least one elongate capillary electrophoresis chip disposed in said device body structure, wherein each said at least one elongate capillary electrophoresis chip comprises: a substrate having a straight main separation channel and an injection channel; a coating layer that covers said substrate, and a plurality of access holes defined in said coating layer for allowing liquid communication between (i) said main separation channel and said injection channel, respectively, and (ii) reservoirs in said plurality of reservoirs that respectively correspond to said separation channel and said injection channel; wherein each said respective elongate capillary electrophoresis chip in said at least one elongate capillary electrophoresis chip is embedded into a corresponding groove such that the plurality of access holes in the respective elongate capillary chip are oriented towards corresponding reservoirs in said plurality of reservoirs; and means for applying and actively controlling a first set and a second set of electric potentials at each of said reservoirs in said plurality of reservoirs.
