New Publication on Photoacoustics Journal

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 8.48)  reporting on the performance of quartz tuning fork (QTF) based laser spectroscopy sensing employing multiple QTFs. To avoid that resonance frequency mismatching of the QTFs degrades the sensor performance, two types of resonance frequency matching method are here proposed. Without regulation, Leggi di piùNew Publication on Photoacoustics Journal[…]

New Publication on Photoacoustics Journal

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 8.48)  reporting on the realization of a compact quartz-enhanced photoacoustic sensor for ppb-level ambient NO2 detection exploiting a blue laser diode. A minimum detectable concentration (1σ) of 7.3 ppb with an averaging time of 1 s is achieved, which can be further improved to Leggi di piùNew Publication on Photoacoustics Journal[…]

New Publication on Photoacoustics Journal

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 8.48)  reporting on the realization of an on-beam quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor based on a custom quartz tuning fork (QTF) with a resonance frequency of 28 kHz, acting as a photoacoustic transducer. H2O, C2H2 and CO2 were detected for a long time and Leggi di piùNew Publication on Photoacoustics Journal[…]

New Publication on Photoacoustics Journal

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 8.48)  reporting on the realization, calibration, and test outdoor of a 19-inches rack sized QEPAS trace gas sensor designed for real-time carbon monoxide monitoring in ambient air. The sensor was tested outdoor in a trafficked urban area for several hours providing Leggi di piùNew Publication on Photoacoustics Journal[…]

New Publication on Applied Physics Review

The PolySense team has just published  a new article on Applied Physics Review journal  (Impact Factor 19.162) reporting on the performance of a custom quartz tuning fork used as a sensitive and broadband infrared photodetector for absorption spectroscopy. A spectrally flat responsivity of ~2.2 kV/W in the spectral range 1.65 µm-10.34 µm was demonstrated, corresponding to a Leggi di piùNew Publication on Applied Physics Review[…]
