The sensor is based on a novel custom quartz tuning fork (QTF) with a mid-infrared quantum cascade laser emitting at 9.55 \u03bcm. With 80-mW optical  power and 300-ms lock-in integration time, the detection limit is achieved to be 2.2 ppb which is the best value reported in the literature so far for NH3 QEPAS sensors. A five-day continuous monitoring for atmospheric NH3 is performed, verifying the stability and robustness of the presented QEPAS-based NH3 sensor.<\/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\/Hammer-shape-QTF_Photoacoustics-2023.pdf\">http:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/Hammer-shape-QTF_Photoacoustics-2023.pdf  <\/a> <\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1024\" height=\"804\" src=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/hammer-shape-QTF-1024x804.jpg\" alt=\"\" class=\"wp-image-2750\" srcset=\"https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/hammer-shape-QTF-1024x804.jpg 1024w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/hammer-shape-QTF-300x236.jpg 300w, https:\/\/polysense.poliba.it\/wp-content\/uploads\/2023\/09\/hammer-shape-QTF-768x603.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The PolySense team has just published\u00a0 a new article on Photoacoustics Journal Elsevier (IF 7.9)\u00a0 reporting on a quartz enhanced photoacoustic spectroscopy (QEPAS) gas sensor designed for monitoring of ammonia (NH3) at ppb-level concentrations.
