The composition of organic compounds absorbed in aerosol particles can provide important clues concerning aerosol-based air pollution studies. The full acquisition electron ionization (EI) mode of the Agilent 7200 Series Accurate Mass GC/Q-TOF MS, in combination with Agilent MassHunter Software tools, enabled a nontargeted workflow to screen a large variety of compounds in a complex particle extract. The EI-MS/MS capability was used to study the structure of unknown compounds based on the accurate mass of product ion fragments.
