The system employs a broadband supercontinuum light source, coupled with an  absorption cell and an optical spectrum analyzer with a resolution of 0.5cm\u22121.  A comparative study between multiple linear  regression (MLR) and partial least-squares regression (PLSR) was conducted to determine the  concentration of each individual component. The results highlight the superior performance  of PLSR in the presence of unbalanced concentration ratios (1:10) among the three alkanes,  achieving mean prediction accuracy of 98%, 93% and 94% for methane, ethane, and propane,  respectively.<\/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\/11\/2025_Opex_supercontinuum-natural-gas.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/2025_Opex_supercontinuum-natural-gas.pdf<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"826\" height=\"651\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/opex-supercontinuum-natural-gas.jpg\" alt=\"\" class=\"wp-image-3700\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/opex-supercontinuum-natural-gas.jpg 826w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/opex-supercontinuum-natural-gas-300x236.jpg 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/opex-supercontinuum-natural-gas-768x605.jpg 768w\" sizes=\"(max-width: 826px) 100vw, 826px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The PolySense team has just published\u00a0 a new article on OSA Optics Express (IF 3.3) reporting on a broadband gas sensor based on direct absorption spectroscopy in the mid-infrared range for the simultaneous detection of methane, ethane, and propane in natural gas-like mixtures.
