    摘要: An infrared radiation gas analyzer for determining the concentration of an ingredient in a sample gas has a sample gas container for containing a sample gas at a temperature at which the ingredient the concentration of which is to be determined will emit infrared radiation in the range characteristic of the ingredient and a window for allowing the infrared radiation to escape from the container. An optical chopper outside said container interrupts the radiation escaping from the container. A pair of filters is positioned in the path of the radiation escaping from the container and spaced transversely of the path, one of the filters transmitting only radiation in the range and the other of the filters transmitting only radiation in a range near to the first mentioned range. Infrared radiation detectors are positioned for receiving the radiation passed by the respective filters and they emit a signal representative of the difference between the radiation received by the respective detectors and which is representative of the concentration of the ingredient the concentration of which is to be determined in the sample gas.

    摘要: A hydrogen gas analyzer having an improved delivery system is provided wherein a plurality of branched passageways can supply a sample cell and an additive fuel to a combustion chamber. Cutoff valves can be activated to control the flow rates through the respective passageways so that when the concentration of hydrogen in the sample gas is high, the flow rate from the additive fuel will be reduced, and when the concentration of hydrogen is low, the flow rate of the sample gas is reduced.
