Aging of atmospheric organic species

We use our fixed-temperature, fixed-volume 7.5 m3 Teflon chamber to probe how oxidative "aging" affects the amounts and chemical composition of atmospheric organic aerosol. A particular focus of our work is the isolation of a single phase in which multigenerational aging occurs (in the gas phase, in aqueous aerosol, etc.), requiring the development of novel approaches for generating high level of oxidants within a given phase.
