AbstractBased on a new spectrophone configuration using a single microresonator (mR) in "on beam" quartz-enhanced photoacoustic spectroscopy (QEPAS), referred to "half on beam QEPAS", a classical acoustic model originated from "orifice ended tube" was introduced to model and optimize the mR geometrical parameters. The calculated optimum mR parameters were in good agreement with the experimental results obtained in "half on beam" as well as conventional "on beam" QEPAS approaches through monitoring of atmospheric H2O vapor absorption. In addition, spectrophone performances of different QEPAS configurations (off beam, on beam and half on beam) were compared in terms of signal-to-noise ratio (SNR) gain.; Based on a new spectrophone configuration using a single microresonator (mR) in "on beam" quartz-enhanced photoacoustic spectroscopy (QEPAS), referred to "half on beam QEPAS", a classical acoustic model originated from "orifice ended tube" was introduced to model and optimize the mR geometrical parameters.
