1. A detection system for a bio-separation device having a separation channel in which bio-separation takes place, comprising:

  • a detection section along a separation channel defining a single detection zone for analytes;

    a plurality of radiation sources;

    excitation means for introducing excitation radiations from the radiation sources at the single detection zone as analytes pass the detection zone;

    detecting means for detecting radiation emissions;

    control means for controlling the radiation sources and detecting means in a manner such that excitation radiations from the radiation sources are introduced at the detection zone in a predetermined sequence and radiation emission from the detection zone associated with each radiation source is detected in a time staggered manner.
