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.
