The PolySense team has just published  a new article on Journal of Lightwave Technology (IF 4.288)  reporting on a new modelling of QEPAS sensors with the optical components semi-integrated with the tuning fork. The design here proposed paves the way to a further level of miniaturization, integration and deployment of QEPAS sensors for application like mobile and on-drone Leggi di piùNew Publication on Journal of Lightwave Technology[…]

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 5.87)  reporting on a quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor for hydrogen sulfide (H2S) detection, exploiting a liquid-nitrogen-cooled THz quantum cascade laser (QCL) operating in pulsed mode. A QEPAS record sensitivity for H2S detection in the THz range of 360 part-per-billion in volume Leggi di piùNew Publication on Photoacoustics Journal[…]

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 5.87)  demonstrating that  quartz-enhanced photoacoustic spectroscopy (QEPAS) is an efficient tool to measure the vibrational relaxation rate of gas species, employing quartz tuning forks (QTFs) as sound detectors.
