Photoacoustic spectrometer for measuring light absorption by aerosol : Instrument description

  title={Photoacoustic spectrometer for measuring light absorption by aerosol : Instrument description},
  author={W. Patrick Arnott and Hans Moosm{\"u}ller and Clarence D. Rogers and Tianfeng Jin and Reinhard Bruch},
Abstract A photoacoustic spectrometer has been developed to measure in situ light absorption by aerosol. The measured quantity is the sound pressure produced in an acoustic resonator caused by light absorption. The current lower detection limit for light absorption is 0.4 Mm which corresponds to an elemental carbon mass density of ≈ 40 ng/m assuming an efficiency for light absorption of 10 m/g. Calibration is performed using simple theory for the instrument along with use of a calibrated… CONTINUE READING
