This paper presents a novel detection scheme for high throughput capillary electrophoresis (CE) applications which utilizes a low-cost LCD projector as the light source. Instead of switching a number of conventional filter sets for multiwavelength detection purpose, a commercial LCD (liquid crystal device) projector is used to digitally modulate the projecting wavelength from the projector. An ultraviolet- visible-near infrared (UV-Vis-NIR) spectrometer is adopted to detect the emitted fluorescence synchronously with the switching light excluding spatial filter sets. A mixed sample composed of three fluorescent dyes and a labeled single-stranded DNA sample were successfully separated and detected using this proposed system.
