Sensor performance was demonstrated using methane in nitrogen gas mixtures, with CH4\u00a0mixing ratios ranging from 75 ppmv to 1% (by volume), measured with an accumulation time of 300 ms, and a minimum detection limit of 34 ppmv subsequently determined. The EW-QEPAS sensor is ideal for miniaturization, as it does not contain any free-space optics and is suitable for gas sensing in harsh environments and where mobility is required. <\/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\/2024\/02\/172_EW-QEPAS_Photoacustics_2004.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/172_EW-QEPAS_Photoacustics_2004.pdf<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1024\" height=\"716\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/EW-QEPAS-1024x716.jpg\" alt=\"\" class=\"wp-image-3098\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/EW-QEPAS-1024x716.jpg 1024w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/EW-QEPAS-300x210.jpg 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/EW-QEPAS-768x537.jpg 768w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/EW-QEPAS.jpg 1374w\" 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 7.9)\u00a0 reporting on an all-fiber-based laser gas analyzer (LGA) employing quartz-enhanced photoacoustics spectroscopy (QEPAS) and a side-polished fiber (SPF).
