| Outline of Final Research Achievements |
We developed instrument using tandem detection of laser-induced fluorescence and incandescence from single particles in real-time. First, a particle is delivered to optical chamber for detection of fluorescence. After measurement of the fluorescence, the particle is delivered to the incandescence detection chamber. This analysis system can provides the information of fluorescent material and black carbon in the particle. We analyzed 43,881 particles in total at ambient air. The particles having fluorescent composition, black carbon, and both of them are 6213(14.2%), 1010(2.3%), and 122(0.3%), respectively.
