The sensor incorporates a compact multi-pass cell measuring 6 cm \u00d7 4 cm \u00d7 4 cm and utilizes a quartz tuning fork (QTF) photodetector. A 1.58 \u00b5m near-infrared distributed feedback (DFB) laser with an optical power of 30 mW serves as the excitation source. The sensor achieved a minimum detection limit (MDL) of \u223c300 ppb at an integration time of 300 ms. By extending the integration time to 100 s, the MDL can be reduced to \u223c25 ppb. <\/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\/2023\/09\/164_Lites-H2S-in-SF6_Photoacoustics_2023.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/164_Lites-H2S-in-SF6_Photoacoustics_2023.pdf<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1024\" height=\"720\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/lites-hs2-1024x720.png\" alt=\"\" class=\"wp-image-2736\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/lites-hs2-1024x720.png 1024w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/lites-hs2-300x211.png 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/lites-hs2-768x540.png 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The PolySense team has just published&nbsp; a new article on Photoacoustics Journal Elsevier (IF 7.9)&nbsp; reporting on an optical sensor based on light-induced thermoelastic spectroscopy for the detection of hydrogen sulfide (H2S) in sulfur hexafluoride&nbsp;(SF6).
