The ultimate instrumentation for trace gas analysis and detection in air quality monitoring as well as industrial process control would be one that can simultaneously provide a sensitive, selective and fast multi-gas measurement with wide dynamic range, all in a compact and robust system. One of the few such promising technologies that can deliver these requirements is laser-based photoacoustic spectroscopy (PAS). In this white paper the PAS technique is presented using the Cobolt Odin™ tunable mid-infrared laser.
