Outline of Final Research Achievements

Aerosols have significant influences on the Earth's radiative budget due to direct and indirect effects. New particle formation is a key process affecting the number concentration of aerosol particles and cloud condensation nuclei. This study is aimed at developing a new system for online measurement of aerosol composition during new particle formation/growth events by combining an aerosol particle classifier and mass spectrometer. We have developed an aerodynamic lens for nanoparticles (nano-ADL) and constructed an aerosol composition analyzer using the nano-ADL and laser desorption mass spectrometer. We also constructed a tandem system of an electrostatic classifier and aerosol particle mass analyzer and developed an automated control software for the system. Although the overall integration of the classifier and mass spectrometer has not been completed, we have established an important technological basis for the study of new particle formation in Asia.
