Abstract
A multiplexed capillary electrophoresis system and process including a bundle of capillary tubes, a power source, a light source, a processor and an array of photodetector elements. Each element of the array generates a pixel signal corresponding to the light passing through the bundle of capillary tubes during the multiplexed capillary electrophoresis process. An A/D converter converts each of the pixel elements signals into a digital value corresponding to the light received by one of the photodetector elements. For each peak digital value, the processor selects five digital values corresponding to the light received by five contiguous photodetector elements and generates output signals. Each output signal corresponds to the light passing through the bundle of capillary tubes and is a function of the selected digital values. As a result, noise and drifts of the pixel signals are minimized.
