A DFB-QCL laser with a central wavelength of 4.61 \u00b5m was employed as an  exciting source with an optical power of 21 mW. The minimum  detection limit (MDL, SNR=1) results 8 ppb at 1 s and reaches a sub-ppb level at 100 s of integration time.  Dynamic response of the system is linear and has been tested up to the concentration of 6 ppm. Saturation  conditions are expected to be reached for CO concentration larger than 100 ppm.  <\/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\/171_CO-in-H2-PAS_Photoacoustics-2024.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/171_CO-in-H2-PAS_Photoacoustics-2024.pdf<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1024\" height=\"747\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/COin-H2-PAS-1024x747.jpg\" alt=\"\" class=\"wp-image-3092\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/COin-H2-PAS-1024x747.jpg 1024w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/COin-H2-PAS-300x219.jpg 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/COin-H2-PAS-768x560.jpg 768w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2024\/02\/COin-H2-PAS.jpg 1334w\" 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 a photoacoustic sensor for the detection of CO impurities in hydrogen.
