Trace gas detection technology is an important approach widely used in the field of air pollution monitoring, industrial production and national security. Quartz enhanced photoacoustic spectroscopy (QEPAS), a highlighted focus of trace gas detection technology, has the potential of toxic and harmful gas detection due to its features of strong anti-interference, small scale and high sensibility. This paper briefly summarizes the fundamentals of QEPAS technology, presents the main performance of QEPAS technology developed in the recent years, and finally discusses the prospects of QEPAS technology according to the current requirement.
