Abstract From the Canadian patent

A fluorometric system for on-line monitoring of biological processes uses a plurality of light sources, each with a different spectral width to , illuminate a sample, the, light sources selected to produce emission of fluorescent light and usually , also dispersed, light, from the illuminated sample. One of the light sources has a wide spectral range. The light sources are operated sequentially or in combination. Spectra acquired from the, emitted light are combined and processed to evaluate properties of the sample such as, concentration of the fluorescing components or particle concentration.
