1. An apparatus for detecting analytes in a sample, comprising:

  • one or more channels having a detection zone;

    one or more irradiation sources disposed for irradiating the detection zone with radiation;

    a detector array disposed for collecting light signals emitted from markers in the detection zone excited by the radiation, the detector array having an output; and

    a system coupled to the detector array for effecting time delay integration of charges on the detector array corresponding to the light signals by accumulating the charges before reading the charges at the output of the detector array, the system effecting time delay integration by moving, relative to one another, the detector array and the detection zone such that the detector array tracks light signals emitted from the markers.
