Abstract
A detector assembly of a spectrometer device which includes a built-in test gas chamber, has a housing defining a chamber with a first end having a first aperture and a second end having a second aperture opposite the first aperture. While light transmissive windows can be mounted in the opposed apertures to enclose the chamber, it is preferred that a focusing lens be mounted in the first aperture and a detector in the second aperture in order to enclose the housing ends and define the chamber. The chamber has a cone-like inner surface tapering from the first aperture to the second aperture. The housing has a test gas inlet in communication with the chamber and disposed proximate the first end thereof. A test gas outlet is in communication with the chamber and disposed proximate the second end. The test gas inlet is so oriented as to introduce test gas into the chamber on a tangent to the first end, first aperture resulting in a tangential flow path direction within the cone-like chamber.
