Single source, single detector chip, multiple-longitudinal channel electromagnetic radiation absorbance and fluorescence monitoring system

The present invention relates to absorbance and fluorescence electromagnetic radiation monitoring systems, and more specifically to photometry, spectrometry and spectrophotometry systems which comprise a sequential combination of a single source of electromagnetic radiation, a multiple longitudinal flow cell channel containing system and a single low cost, low drift electromagnetic radiation detector chip. Disclosed is a multiple longitudinal flow cell channel electromagnetic radiation absorption or fluorescence monitoring system wherein a source of electromagnetic radiation is positioned to input electromagnetic radiation to each of the longitudinal flow cell channels, and wherein a single low cost, low drift, preferably linear and sensitized to UV, array detector system is positioned to directly simultaneously monitor electromagnetic radiation from at least two of the longitudinal flow cell channels, at different locations thereupon.
