    Abstract: A gas sample chamber (10) for use in a gas analyzer consists of an elongated hollow tube (21) having an inwardly-facing specularly-reflective surface (22) that permits the tube to function also as a light pipe for conducting radiation from a source (20) to a detector (16) through the sample gas. A number of apertures (24) 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 (28) that spans the apertures in the hollow tube. Condensation of the sample gas components is prevented by heating the sample chamber electrically to a temperature above the dew point of the component of concern.

    Abstract: A radiation arrangement suitable for emitting IR radiation has a flat radiation source (2), the radiation emitted from which is deflected in at least one predetermined direction by a reflector (4); said reflector consists of a body, the circumference of which becomes smaller towards the beam outlet and the reflective surface of which is substantially surrounded by the radiation source; in an axisymmetrical arrangement, the distance between the radiation source and the axis of the reflected beam is greater than the radius of the reflector component arranged symmetrically in rotation along the optical axis. The radiation body may consist thereby of a resistive coating (2) on an electrically insulating substrate (3) or a self-supporting resistive strip or wire. An essential advantage here is that there is a relatively large area for the generation of IR radiation which can be bunched into a high-intensity beam by the reflector arrangement, as is necessary in measuring instruments, e.g. gas analysers.
