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[…]
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[…]
