A New Photoacoustic Soot Spectrophone for Filter-Free Measurements of Black Carbon at 880 nm
A new photoacoustic soot spectrometer (PASS) operating at 880 nm was developed, for the first time, for filter-free measurements of black carbon (BC). The performance of the developed PASS was characterized and evaluated using a reference aethalometer AE51 on incense smoke in the air. An excellent c...

| description | A new photoacoustic soot spectrometer (PASS) operating at 880 nm was developed, for the first time, for filter-free measurements of black carbon (BC). The performance of the developed PASS was characterized and evaluated using a reference aethalometer AE51 on incense smoke in the air. An excellent correlation on the measurement of incense smoke was found between the two instruments in comparison with a regression coefficient of 0.99. A 1 σ detection limit of 0.8 µg m<sup>−3</sup> was achieved for BC measurement at a time resolution of 1 s. It can be further reduced to 0.1 µg m<sup>−3</sup>, using a longer integration time of 1 min. |
