The PolySense team has just published a new article on Photoacoustics Journal Elsevier (IF 9.94) reporting on the development of a highly sensitive hydrogen sulfide (H2S) gas sensor exploiting the doubly resonant photoacoustic spectroscopy technique and using a near-infrared laser emitting at 1578.128 nm. We achieved a minimum detection limit of 10 part per billion in concentration. A comparison among the state-of-the-art H2S sensors using various spectroscopic techniques confirmed the record sensitivity achieved in this work.
