The PolySense and Polysense Innovations teams have just published  a new article on Journal of Breath Research (IOP) reporting on a computational method to identify volatile organic compound (VOC) artifacts introduced by breath sampling hardware. To exclude endogenous biological variability, ambient air was collected using two sampling devices working in the same experimental conditions: the Leggi di piùNew Publication on Journal of Breath Research[…]

The PolySense and Polysense Innovations teams have just published  a new article on Optics & Laser Technology journal (IF 5.0) reporting on a comparison between quartz-enhanced photoacoustic spectroscopy (QEPAS) and beat-frequency QEPAS (BF-QEPAS) techniques for the sequential detection of methane (C1) and ethane (C2) in the near-infrared spectral range. Experiments were performed using a laser Leggi di piùNew Publication on Optics & Laser Technology Journal[…]

The PolySense and Polysense Innovations teams have just published  a new article on ACS Sensors Journal (IF 9.1)  reporting on a compact differential photoacoustic gas sensor for end-tidal carbon dioxide (ETCO2) and end-tidal oxygen (ETO2) monitoring. The sensor employs a dual-resonator photoacoustic cell with resonant frequencies of 4110 and 13,115 Hz for selective ETCO2 and Leggi di piùNew Publication on ACS Sensors journal[…]
