The PolySenSe Team has visited the THORLABS Headquarter to discuss future development exploiting the New Lab facility that will open soon @ the Physics department of Bari.
The PolySense team has just published a new article on Photoacoustics Journal reporting on a comparison between piezoelectric and interferometric readouts of vibrations in quartz tuning forks (QTFs) for quartz-enhanced photoacoustic (QEPAS) trace gas detection.

The PolySense team has just published a new article on Photoacoustics Journal reporting on multi-gas QEPAS detection of methane and nitrous oxide using a quantum cascade laser array. A methane detection sensitivity of 200 ppb and 60 ppb for nitrous oxide were achieved with a 10 s lock-in integration time.

The PolySense team has just published a new article on Applied Physics Letters reporting on a highly sensitive trace gas sensor based on light-induced thermoelastic spectroscopy (LITES) and a custom quartz tuning fork (QTF). A minimum detection limit of 325 ppb was achieved at an integration time of 1 s, nearly one order of magnitude Leggi di piùNew Publication on Applied Physics Letters[…]
