ABSTRACT:
A gas analyzer system for providing a spectroscopic analysis of the sample gas. This analysis is accomplished by first introducing the sample gas into the inlet of the system and transporting it to a spectral analyzer. The sample gas is then spectrally analyzed and the analyzer outputs a signal indicative of a radiation intensity spectrum associated with the analyzed sample gas. A processing unit uses the analyzer signal to detect the presence of one or more prescribed gases and to determine the concentration of each of the prescribed gases in the sample gas. Next, the reacting agent is supplied to the sample gas to convert one or more gases whose presence in the sample gas cannot be detected via spectral analysis due to the masking effects other gases present in the sample gas. The masked gases are converted to secondary gases at least one of which is readily detectable via spectral analysis. This converting process occurs in the time it takes for the sample gas to transit uninterrupted through the system to the analyzer. The modified sample gas is spectrally analyzed, and the processing unit detects the presence of the masked gases and determines the concentration of each. The system may be employed to monitor certain environmental gases contained within industrial emission. In such a case, the prescribed gases are nitrogen dioxide and sulfur dioxide, and the masked gases are nitric oxide, ammonia, and hydrogen sulfide.
