Abstract
The size distributions of airborne nanoparticle are influenced by pollutant sources and
atmospheric environment and are variable to different time and sites. There are some aerosol
generators could generate monodisperse or polydisperse aerosols, but no one could control the
size distribution pattern to simulate the ambient air of different characteristics. The nanoparticle
generator that can control the size distribution pattern of particle generated and simulate different
environment. The nanoparticle generator can afford a stable aerosol source to be used to evaluate
the performance of air pollution control devices and the human health effects of ultrafine
particles.
Electrospray aerosol generator is a monodisperse aerosol generator. We propose to adopt its
liquid supply system into a programmable multi-supply system. The aerosols generated by the
generator are still monodisperse but with variable concentration. After the aerosols are dried in
the test chamber, it leaves the aerosols of polydisperse. By changing the concentration of injected
liquid in series in each cycle time, we can get a specific aerosol size distribution pattern and try
to resembling atmospheric environment.
