A gas sample chamber for use in a gas analyzer consists of an elongated hollow tube having an inwardly-facing specularly-reflective surface that permits the tube to function also as a light pipe for conducting radiation from a source to a detector through the sample gas. A number of apertures in the wall of the elongated hollow tube permit the sample gas to enter and exit. Particles of smoke and dust of a size greater than 0.1 micron are kept out of the chamber by use of a semi-permeable membrane that spans the apertures in the hollow tube. Condensation ...


A multi-channel diffusion-type gas sample chamber for conducting radiation through a gas, comprising in combination: an elongated hollow tube having a wall, composed of a gastight material, and having an inwardly-facing specularly-reflective surface that conducts radiation introduced at one end of said elongated hollow tube toward the other end with high efficiency by means of multiple reflections from said inwardly-facing specularly-reflective surface, said elongated hollow tube having a plurality of apertures extending through the wall and located inte...
