CO Detection in SF6 Using Quartz-enhanced Photoacoustic Spectroscopy – a case study

Researchers from China and Italy have developed a highly sensitive and selective optical sensor using quartz-enhanced photoacoustic spectroscopy (QEPAS) for carbon monoxide (CO) detection in sulfur hexafluoride (SF6 ) decomposition. High-voltage apparatuses, utilizing SF6 as gas-insulating medium, require rapid and continuous monitoring. Detecting CO as one of the SF6 decomposition products allows early diagnosis of Leggi di piùCO Detection in SF6 Using Quartz-enhanced Photoacoustic Spectroscopy – a case study[…]
