Summary:PCT No. PCT/US92/08589 Sec. 371 Date Mar. 29, 1994 Sec. 102(e) Date Mar. 29, 1994 PCT Filed Oct. 8, 1992.An apparatus and method of aligning a capillary with respect to a radiation source. More particularly, the capillary is aligned with a laser beam for laser induced fluorescence detection. The scatter or transmitted light pattern of the laser beam with respect to the capillary tube is utilized to determine optimum alignment. photosensors may be implemented to detect the light pattern which represents optimum alignment. For dynamic alignment during electrophoresis, the photosensors provide feedback to a controller which controls a positioning mechanism for alignment of the capillary.
