Our platform supports both field observations and laboratory studies by integrating online gas- and particle-phase mass spectrometry, oxidation flow reactor and offline ultrahigh-resolution mass spectrometry. Online measurements characterize the composition and evolution of atmospheric gases and particles in real time, while oxidation flow reactor experiments are used to investigate secondary formation and chemical aging. Complementary GC- and LC-based analyses enable targeted and nontargeted molecular-level characterization of organic aerosol constituents, source markers, chromophores, and atmospheric transformation products.
