New Publication on Optics Letters

The PolySense team has just published  a new article on OSA Optics Letters Journal reporting on a novel multi-pass quartz-enhanced photoacoustic spectroscopy-based trace gas sensor . The multi-pass configuration allows the laser beam to pass through the QTF prong spacing six times. Compared to a conventional QEPAS measurement, the MP-QEPAS technique provided an enhancement of signal Leggi di piùNew Publication on Optics Letters[…]

New Publication on Photoacoustics Journal

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 5.87)  reporting on a comparison between Quartz-Enhanced Photoacoustic Spectroscopy (QEPAS) and Photothermal Spectroscopy (PTS). Compact QEPAS and PTS detection modules were realized and integrated in a gas sensor system for detection of carbon monoxide (CO). Performance was compared and ultimate detection limits Leggi di piùNew Publication on Photoacoustics Journal[…]

New Publication on Journal of Lightwave Technology

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[…]

New Publication on Photoacoustics Journal

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[…]
