The PolySense team has just published a new article on Photoacoustics Journal Elsevier (IF 8.48) reporting on the realization, calibration, and test outdoor of a 19-inches rack sized QEPAS trace gas sensor designed for real-time carbon monoxide monitoring in ambient air. The sensor was tested outdoor in a trafficked urban area for several hours providing results comparable with the daily averages reported by the local air inspection agency, with spikes in CO concentration correlated to the passages of heavy-duty vehicles.
