A multiple-channel spectrometer assembly for analyzing a plurality of sample
flows.
The assembly includes a plurality of spectrometer channels, each fluidly connectable
to a respective one of the sample flows. Each channel has a sample inlet and a
sample outlet connectable to a respective one of the sample flows. Each channel
has a chassis and a light source mounted to the chassis. A spectrometer module
is adjacent to each chassis and is optically coupled a light outlet portion of
the light source. The spectrometer module has an optical inlet axially coupled
to the light outlet portion to receive light from the light source. A high-pressure
flow cell assembly is positioned adjacent to the chassis between the light source
and the spectrometer module to emulate a fiber optic cable therebetween. The flow
cell assembly has a flow passageway in fluid communication with the sample inlet
and sample outlet. The flow passageway is configured to receive one of the sample
flows therethrough so the light from the light source passes through the sample
flow prior to being received by the spectrometer module for analysis of the light
absorption profile of the sample.
