ABSTRACT:
A multi-pass optical cell for measuring the concentration of one or more species in a fluid to be monitored includes a sample region; a source of collimated radiation; a detector device for sensing the intensity of the radiation; at least two reflective surfaces for reflecting in a first direction in the sample region a number of times the radiation from the source and delivering it to the detector device.
