This dual-domain approach enables: (i) selective identification and quantification of light alkanes in complex natural gas mixtures; (ii) sub-ppm detection of propane using a single interband cascade laser emitting at 3.367\u202f\u00b5m; and (iii) isotopic discrimination between methane isotopologues (<sup>12<\/sup>CH\u2084 and\u00a0<sup>13<\/sup>CH\u2084) employing a quantum cascade laser operating near 7.81\u202f\u00b5m. By overcoming spectral overlap through chromatographic separation and leveraging QEPAS\u2019s intrinsic sensitivity, the GC\u2013QEPAS configuration offers a high-performance alternative to GC\u2013FID\/MS for in situ compositional and isotopic gas analysis.  <\/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\/2026\/06\/1-s2.0-S0925400526008579-main.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2026\/06\/1-s2.0-S0925400526008579-main.pdf<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"822\" height=\"671\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2026\/06\/GC-QEPAS.jpg\" alt=\"\" class=\"wp-image-4006\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2026\/06\/GC-QEPAS.jpg 822w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2026\/06\/GC-QEPAS-300x245.jpg 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2026\/06\/GC-QEPAS-768x627.jpg 768w\" sizes=\"(max-width: 822px) 100vw, 822px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The PolySense and Polysense Innovations teams have just published\u00a0 a new article on Sensors and Actuators B Chemical Journal (IF 7.7) reporting on a hybrid sensing platform that integrates GC with Quartz-Enhanced Photoacoustic Spectroscopy (QEPAS) combining the temporal separation capabilities of GC with the high sensitivity and molecular selectivity of mid-infrared laser spectroscopy.
