Abstract
In contrast to conventional absorption spectroscopy methods, photoacoustic spectroscopy (PAS) measures the absorbed light power directly, which makes the technique highly sensitive and also enables small sample volumes [1]. These properties are important in multicomponent trace-gas analysis, which is possible in PAS using a broadband light source together with a Fourier transform spectrometer (FTS) as a light modulator. A cantilever-enhanced photoacoustic spectroscopy (CEPAS) is a non-resonant photoacoustic technique enabling sensitive detection over a wide range of frequencies [2]. The CEPAS technique together with FTS has so far been used only with conventional infrared radiators, which suffer from poor spectral power density [3].
