ICARUS Chamber Experiment: Caltech Atmospheric Chamber_20130329_cis-beta IEPOX_None_Ammonium sulfate_DarkReactiveUptake_RH86

Goals: This experiment was performed to assess the reactive uptake behavior of cis beta-IEPOX that was synthesized for the experiment. Different particle inorganic compositions (mainly ammonium sulfate or AS) and different particle water content were investigated. Particles are injected into the chamber as deliquesced droplets (through a wet wall denuder) and they stabilize to their equilibrium particle liquid water content depending on their hygroscopicity.Summary: Large organic aerosol (OA) growth was observedOrganization: Caltech Atmospheric Chamber Lab Affiliation: California Institute of Technology, Pasadena, CA Chamber: Near/Far Bag 2012-2015 (Tran)Experiment Category: Condensed-phase chemical reaction, Multiphase chemical reaction Oxidant: None Reactants: cis-beta IEPOX Reaction Type: Heterogeneous oxidation, Other aqueous/aerosol phase Relative Humidity: 86 Temperature: 22 Seed Name: Ammonium sulfate Pressure: 750 Torr
