摘要：A multi-channel capillary electrophoresis apparatus is disclosed. The apparatus includes a capillary array assembly comprising a plurality of capillaries, each capillary having a capillary outlet, and an outlet support for supporting the capillary outlets. The apparatus further includes a cuvette defining a receiving slot, a gap region and a detection zone, where the receiving, slot is adapted to removably receive the outlet support, and wherein when the outlet support is inserted into the receiving slot, the capillary outlets are positioned in the gap region in proximity to the detection zone, and a flow channel is formed by the outlet support and the receiving slot such that the flow channel is in fluid communication with the gap region. In addition, the apparatus includes a front plumbing block in fluid communication with the flow channel for supplying a fluid flow through the gap region sufficient to transport material downstream the capillary outlets to the detection zone.
