Cantilever-enhanced Photoacoustic Detector for Light-absorbing Aerosols

We present here the first application of cantilever-enhanced photoacoustic spectroscopy for aerosol absorption measurements. A noise equivalent absorption of 1.3x10-10 cm-1 (one standard deviation) is reached with 20 s sampling time.
