Soot mass concentration sensor using quartz-enhanced photoacoustic spectroscopy [PDF]

In this work, a measurement setup for a miniaturized soot sensor with QEPAS is reported. Specifically, measurements of mass concentrations of soot from a miniCAST soot generator are compared with those from an MSS, which is a common method to measure ...

QEPAS gas sensors for air quality monitoring

, 2020
L’activité humaine, à l’échelle d’un particulier ou à l’échelle industrielle, libère de nombreuses molécules dans l’atmosphère. Même une petite quantité de certaines de ces molécules peut dégrader la qualité de l’air. Des capteurs de gaz sont donc essentiels pour mesurer la concentration de ces molécules dans l’environnement.
