Resonant photoacoustic spectrometer enhanced by multipass absorption for detecting atmospheric CH(4) at the ppb-level

A resonant photoacoustic spectrometer (PAS) was developed for detecting trace atmospheric CH(4). The sensitivity of the PAS was significantly increased via a Herriott-type multipass cell with a beam pattern concentrated in the cavity. The effective optical pathlength of the PAS can be optimized to 6...
