摘要：

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 sigma detection limit of 0.8 mu g m(-3) was achieved for BC measurement at a time resolution of 1 s. It can be further reduced to 0.1 mu g m(-3), using a longer integration time of 1 min.
