| Abstract: | The present article describes a method to measure fluorescence characteristics of aerosol particles in air, and a technique used to measure the aerodynamic diameter of aerosol particles. Experiment system design details and measurement plans were given. Fluorescence intensity spectra were compared with particle aerodynamic diameter spectra. Aa analysis method of fluorescent percentage, which is useful to identify biological aerosol particles, was also discussed. |
