Tunable, narrow bandwidth mid-IR laser sources for compact trace gas analysis systems with ppb sensitivity
10 June 2016
This article is brought to you by:
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).
