    摘要： Apparatus for cooling a bundle of capillary tubes to prevent overheating of the tubes during a parallel capillary electrophoresis procedure. The apparatus includes a jacket of thermally conductive solid material comprising mating jacket members movable between an open position in which the jacket members are separated to allow placement of the bundle in the jacket and a closed position in which the jacket members are mated together and the bundle is disposed inside the jacket in thermally conductive relation with the jacket. Window openings in the mating jacket members define a window to permit the passage of light through the window and the capillary tubes of the bundle at the location of the window.

    摘要： A multiplexed capillary electrophoresis system with cooling sufficient to prevent overheating during chiral separation. The system includes a thermally insulated enclosure enclosing a bundle of capillary tubes, a light source and photodetector. A heat transfer system is provided for cooling closely spaced portions and spread apart portions of the capillary tubes to an extent sufficient to prevent overheating of the tubes and contents thereof due to the heat generated during chiral separation.

    摘要： 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.
