Dual mode scanning optical system for capillary electrophoresis

Abstract

A dual-mode capillary electrophoresis system () is disclosed, which comprises a plurality of capillaries for receiving a plurality of samples, a UV radiation source () for generating UV radiation along a first path (PB), a laser light source () for generating laser radiation along a second path (PA), and a galvanometric mirror () configured to receive radiation from said UV radiation source along said first path and to receive light from said laser light source along said second path, and to direct said received UV radiation and said laser light onto a common optical path, said galvanometric minor further being configured to scan said UV radiation and said laser light sequentially over said plurality of capillaries. The system can further include a detector () for detecting the UV radiation as well as a detector () for detecting fluorescent radiation via optical fibers () emitted by the samples in response to laser excitation.
