[email protected]In this manuscript, the implementation of an optical leak sensor based on QEPAS is reported. The QEPAS sensor was integrated into a vacuum-seal test station for mechanical valves. Sulfur hexafluoride (SF 6) was selected as the leak tracer gas and a 1% SF 6 in N 2 mixture was employed.
