Photoacoustic spectroscopy: Trace CO detection by using 10 mW near-infrared laser and cantilever beam
Sulfur hexafluoride (SF6) is commonly used in gas insulated switchgears (GIS) as an insulating medium. When local overheating or partial discharge occurs in GIS, SF6 may be decomposed into various products including CO. In this paper, based on the photoacoustic (PA) effect of gas molecules, the infr...
