Using 1 % of the laser source as an optical syn chronization signal, kilometer-scale remote gas detection was achieved, overcoming the challenges of long-  distance real-time detection in complex environments with conventional QEPAS. A time-sharing OSSD-QEPAS  system for sewer methane detection was subsequently developed and achieving  a detection limit of 445 ppb with a 300-ms averaging time. Continuous methane  measurements covering a 14-hour period at two different sewer locations on campus were performed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> The following link provides access to the article:    <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/03\/Remote-QEPAS-Sewer_Photoacoustics_2025.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/03\/Remote-QEPAS-Sewer_Photoacoustics_2025.pdf<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1024\" height=\"796\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/03\/Remote-QEPAS-SEWER-1024x796.png\" alt=\"\" class=\"wp-image-3464\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/03\/Remote-QEPAS-SEWER-1024x796.png 1024w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/03\/Remote-QEPAS-SEWER-300x233.png 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/03\/Remote-QEPAS-SEWER-768x597.png 768w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/03\/Remote-QEPAS-SEWER.png 1834w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The PolySense team has just published\u00a0 a new article on Photoacoustics Journal Elsevier (IF 7.1)\u00a0 reporting on a novel optical synchronized signal demodulation (OSSD) method applied in quartz-enhanced photoacoustic spectroscopy (QEPAS) for remote gas sensing.
