The PolySense team has just published a new article on Forntiers in Environmental Chemistry Journal (IF 4.24) reporting on an innovative sensor box employing two acoustic detection modules connected in series for quartz-enhanced photoacoustic multi-gas detection. To demonstrate the sensor versatility, simultaneous detection in air of methane and nitric oxide (NO), is reported.
Minimum detection limits of 48 ppb and 11 ppb for methane and nitric oxide detection were achieved, respectively. The sensor box operation was tested by analysing ambient air.
