New Publication on Photoacoustics Journal

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.

New Publication on Applied Physics Letters

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[…]
