The system employs a distributed feedback diode laser operating at 1.278 \u03bcm, targeting the HF first-overtone absorption line, and an optimized White cell having a 345\u202fmm length cavity and providing an effective optical path length of 76\u202fm.  The minimum detection limit was determined to be 48 ppb (3\u03c3), highlighting superior sensitivity among near-infrared HF detection approaches. These results highlight the system\u2019s strong potential for high-purity gas analysis and real-time process control in semiconductor environments.<\/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\/HFsensor-in-GEF4_2025.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/HFsensor-in-GEF4_2025.pdf<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"837\" height=\"660\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/HF-in-GeF4.jpg\" alt=\"\" class=\"wp-image-3694\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/HF-in-GeF4.jpg 837w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/HF-in-GeF4-300x237.jpg 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2025\/11\/HF-in-GeF4-768x606.jpg 768w\" sizes=\"(max-width: 837px) 100vw, 837px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The PolySense team has just published\u00a0 a new article on Sensors and Actuators B Chemical Journal Elsevier (IF 7.7)\u00a0 reporting on a highly sensitive gas sensor based on tunable diode laser absorption spectroscopy (TDLAS) for HF monitoring in GeF\u2084 matrices.
