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 be 0.3 ppb with an averaging time of 590 s. Continuous measurements covering a five-day period are performed to demonstrate the stability and robustness of the reported NO2 sensor system.
