Short summary
Chemical analysis of sub-30 nm aerosol particles is important for understanding aerosol nucleation and early growth, yet it is still an experimental challenge. In this study, we present a novel device for size resolved chemical analysis of nucleation and Aitken mode particles (from ~10 to ~30 nm) while allowing gas phase measurements with the same detector. Particles are charged, size selected, electrostatically collected and then thermally desorbed in a carrier gas.
