Abstract

A gas analysis system and method use foreground broadband gas monitoring and background selective gas analysis. The foreground broadband monitoring indicates concentrations of a class of chemicals or contaminants in a gas sample, provides real-time warnings of contaminants, and can activate the background selective analysis. Separate broadband detectors and gas analyzers can respectively perform broadband monitoring and selective analysis. To reduce system components, a broadband detector that performs broadband monitoring switches to measure concentrations of chemicals output from a separation device for the selective analysis.
