Abstract
An infrared gas analyzer is described wherein infrared energy is directed through a sample cell from a source at one end thereof. A detector at the opposite end of the sample tube monitors infrared energy of at least one pre-selected wavelength in order to produce a signal representative of the infrared energy passing through the sample cell. The analyzer is of modular construction including a disposable sample cell, an infrared source housing, a detector housing and printed circuit boards mounting signal processing components for the analyzer. A mounting base is adapted for receiving the sample tube, housings and printed circuit boards in operating alignment and interconnection with each other, detents positively securing the components in place.
