Patent ID: 6894777

Claim:
A multiple-channel spectrometer assembly for analyzing a plurality of sample flows, comprising: a plurality of spectrometer channels each being fluidly connectable to a respective one of the plurality of sample flows, each channel having: a sample inlet and a sample outlet connectable to a respective one of the sample flows; a chassis; a light source having a light outlet portion; a spectrometer module mounted to the chassis and optically aligned with the light source, the spectrometer module having an optical inlet axially aligned with the light outlet portion of the light source; and a flow cell assembly adjacent to the chassis intermediate the light source and the spectrometer module, the flow cell having a flow passageway in fluid communication with the sample inlet and sample outlet and configured to receive one of the plurality of sample flows therethrough, the flow passageway being positioned between the light source and the spectrometer, the flow cell assembly being configured to direct light from the light source toward the spectrometer module as the sample flow moves through the flow passageway; and a signal processor coupled to each of the spectrometer modules and configured to receive data from each spectrometer module.
