Abstract:
1. A capillary electrophoresis system comprising: a plurality of separation channels configured to carry a buffer solution; a single shared buffer reservoir communicating with all of the plurality of plurality of separation channels and containing the buffer solution; a sample loading channel communicating with each of said plurality of separation channels; a loading circuit comprising a plurality of electrodes configured to induce an electric field across said sample loading channel sufficient to deliver a sample to said plurality of separation channels; a plurality of detectors, one each of said plurality of detectors proximate to each of said separation channels and configured to detect an analyte; a driver circuit comprising a plurality of electrodes configured to induce an electric field across each of said plurality of separation channels, said electric field useful to cause analytes from said samples to migrate in each of said plurality of separation channels towards one of said detectors; and, at least a controller configured to record data from each of said plurality of detectors, to control said plurality of detectors, and to control said driver circuit; wherein said sample loading channel is defined by a plurality of legs, each leg having substantially the same electrical resistance when they contain the same fluid.
