ABSTRACT:
A gas analyzer capable of measuring select properties of gas includes a source for emitting a beam of radiation and a detector for receiving the radiation, with the beam aligned to impinge the detector. A housing for enclosing the beam has two apertures permitting the gas to enter the housing through one of the apertures to intercept the beam, and to exit from the housing through the other aperture. Nozzles capable of generating fluid curtains are positioned to intercept the beam and are positioned to define a zone in the housing within which zone the gas is confined.
