Abstract
A capillary electrophoresis system includes a plurality of capillaries arranged in parallel on a vertical plane at an identical distance from each other, each of which has a sample injection end immersed in a cathode bufferand pointed downward vertically to facilitate connection between the cathode bufferand a sample solution. The sample elution end is connected via a pump blockand a connection tubeto an anode bufferThe height is made identical between the liquid levels for buffersandto prevent movement of the separation medium in the capillaries. The sample introduced from the sample injection endmoves upward vertically via electrophoresis to the sample elution end in the capillary and is passed through and detected at the fluorescence detection position. The effective separation length is thus decreased to 10 cm or less to attain high throughput.
