A nanoparticles aerosol generator is disclosed. The nanoparticles aerosol generator includes an evaporation chamber having a wall, a container containing a source material, and a heating device configured to heat the source material. The nanoparticles aerosol generator also includes a carrier gas source configured to blow a carrier gas toward the source material to generate a nanoparticles aerosol with nanoparticles of the source material suspended therein. The nanoparticles aerosol generator further includes a dilution gas source configured to supply a dilution gas into the chamber to flow substantially along the wall within the chamber and to dilute the nanoparticles aerosol. |
