1. In a method for rapidly detecting light from a channel of capillary dimensions, where a plurality of individual components of a mixture comprising different fluorophores emitting different wavelengths move along said channel at spaced apart intervals for an exposure time of less than about 500 msec, where the light appears as a band, the improvement which comprises:

  • dividing the light from said bands into different wavelength ranges, separately detecting each wavelength range with different CCD cameras, where the light illuminates a spot which included from 2 to 100 pixels in a row and binning the signal received along the rows of pixels to provide a total for said band; and

    transmitting the signal to a data processor for detecting said band.
