Abstract
An apparatus and method are set for determining the centers of capillaries in a multicapillary electrophoresis array for subsequent rapid and efficient laser induced fluorescence interrogation. A galvometric scanner reflects the laser beam to scan the array during an alignment pre-scan. The beam interacts with the array to produce an intensity pattern indicative of the capillary centers. The scanner positions corresponding to the capillary centers determined during the pre-scan is recalled to direct the beam during the interrogation scan to the column centers.
