Partial least squares regression (PLSR) was employed as a multivariate statistical tool to accurately determine the concentrations of C1 and C2 in the mixtures, compensating the matrix relaxation effects. The achieved results extend the range of C1 and C2 concentrations detectable by QEPAS technique up to the percent scale.<\/span><\/p>\n<p>The following link provides access to the article:<\/p>\n<p><a href=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2022\/03\/140_High-concentr-QEPAS_Photoacoustics-2022.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2022\/03\/140_High-concentr-QEPAS_Photoacoustics-2022.pdf<\/a><\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-2195\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2022\/03\/high-conc.jpg\" alt=\"\" width=\"1878\" height=\"1795\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2022\/03\/high-conc.jpg 1878w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2022\/03\/high-conc-300x287.jpg 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2022\/03\/high-conc-768x734.jpg 768w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2022\/03\/high-conc-1024x979.jpg 1024w\" sizes=\"(max-width: 1878px) 100vw, 1878px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The PolySense team has just published\u00a0 a new article on Photoacoustics Journal Elsevier (IF 8.48)\u00a0 reporting on a\u00a0quartz enhanced photoacoustic spectroscopy (QEPAS) sensor capable to detect high concentrations of methane (C1) and ethane (C2).\u00a0In the concentration ranges under investigation (1%- 10% for C1 and 0.1%- 1% for C2), both linear and nonlinear responses of the <a href=\"https:\/\/polysense.poliba.it\/index.php\/2022\/03\/23\/new-publication-on-photoacoustics-journal-8\/\" rel=\"nofollow\"><span class=\"sr-only\">Leggi di pi\u00f9New Publication on Photoacoustics Journal<\/span>[&hellip;]<\/a><\/p>\n","protected":false},"author":1,"featured_media":973,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-2202","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-senza-categoria"],"_links":{"self":[{"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/posts\/2202","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/comments?post=2202"}],"version-history":[{"count":1,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/posts\/2202\/revisions"}],"predecessor-version":[{"id":2203,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/posts\/2202\/revisions\/2203"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/media\/973"}],"wp:attachment":[{"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/media?parent=2202"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/categories?post=2202"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/polysense.poliba.it\/index.php\/wp-json\/wp\/v2\/tags?post=2202"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
