ABSTRACT:
A capillary electrophoresis apparatus of the invention has: a plurality of capillaries which are filled with a migration medium and have first ends into which samples are injected and second ends in which components included in the samples are eluted; a sheath flow cell in which the second ends are arranged in a straight line at first predetermined intervals and are terminated and a sheath flow is formed; a buffer solution vessel for housing a buffer solution flowing in the sheath flow cell; a drain vessel housing the buffer solution flowed from the sheath flow cell; an optical system emitting laser light to a part near the second ends; and a fluorescent detection system for detecting fluorescent light generated from fluorophore labelling the components included in the sample eluted near the second ends by the emission of laser light, wherein the buffer solution flows from the lower part to the upper part of the sheath flow cell, thereby forming a sheath flow in the sheath flow cell.
