Short summary

We present a new method to continuously generate N₂O₅ in the gas phase that is injected into a reactor where it decomposes to generate nitrate radicals (NO₃). To assess the applicability of the method towards different chemical systems, we present experimental and model characterization of the integrated NO₃ exposure and other metrics as a function of operating conditions. We demonstrate the method by characterizing secondary organic aerosol particles generated from the β-pinene + NO₃ reaction.
