Short summary
This study describes a new volatility-based method to directly examine the composition and corresponding hygroscopic contribution of mixed aerosol components. Measurements of chamber-generated secondary organic aerosol and coastal marine aerosol demonstrated effective separation of both internal and external mixtures. In each case, the findings enabled composition-based models to reliably reproduce observed particle hygroscopicities.
