Abstract A versatile infrared analyzer employing gas-filter correlation techniques has been designed and constructed to measure concentrations of pollutant gases from a variety of sources. The spectral bandpass is determined by an adjustable grating assembly. By interchanging cell windows, radiant energy sources, gratings, interference filters, and detectors, nearly any desired spectral bandpass between 0.3 micrometers and 11 micrometers can be obtained. Spectral curves of transmittance can also be scanned. A multiple-pass sample cell provides sample paths between approximately 4 m and 40 m. Shorter sample cells can also be employed. An H2O monitor measures the concentration of H2O in the multiple-pass sample cell and automatically accounts for interference by H2O in the measurement of other gas concentrations. Tests have been performed on the measurement of formaldehyde, vinyl chloride and ammonia. The minimum detectable concentration of formaldehyde in automotive exhaust is approximately 0.05 ppm.
