A diffusion flame propane soot generator is presented. It can operate under different burning conditions and produce a variable aerosol output. The aerosol flow can be changed gradually from an unimodal flow of large soot particles to a bimodal flow of soot particles mixed with small droplets of PAHs. The existence of the small PAH droplets suggests that no sulfuric acid nuclei (as observed for Diesel engines) are necessary to nucleate PAHs.
