摘要
A combustion burner for the production of submicron polydisperse aerosol particles was developed and experimentally studied in this paper. The sample particles from the generator were characterized by the scanning electron microscope ( SEM) ,the energy dispersive spectroscopy ( EDS) ,and the long electrical mobility spectrometer ( L-EMS) for morphology,chemical composition,and particle number concentration and size distribution,respectively. It was found from the SEM image that a large portion of the particles were non-spherical and were agglomerated. Polydisperse aerosols with particle number concentrations of approximately 10 14 particles /m 3 were obtained. The average diameter of the generated particles obtained by the L-EMS is in the range of approximately 5 nm to several hundred nanometers.
