Environmental Monitoring of Methane with Quartz-Enhanced Photoacoustic Spectroscopy Exploiting an Electronic Hygrometer to Compensate the H<sub>2</sub>O Influence on the Sensor Signal

A dual-gas sensor based on the combination of a quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor and an electronic hygrometer was realized for the simultaneous detection of methane (CH<sub>4</sub>) and water vapor (H<sub>2</sub>O) in air. The QEPAS sensor employed an...
