The PolySense team has just published a new article on Sensors reporting on a the realization of 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 (CH4) and water vapor (H2O) in air. The sensor was tested by performing prolonged measurements of CH4 and H2O over 60 h to demonstrate the effectiveness of this approach for environmental monitoring applications..
