ABSTRACT:
In an improved flow microfluorometer, the variation in fluorescence intensity of a particle as a function of wavelength is transduced to an electrical variation in time where time in the signal variation is proportional to wavelength. The resulting spectrum may be a line spectrum or a continuous spectrum. The temporal waveforms can then be analyzed to extract data on a single particle, and this information in turn can be used as a means to identify the particle for sorting.
