ICARUS Chamber Experiment: Ng Research Group_20220716_alpha-Pinene/Limonene_Nitrate radical_Ammonium sulfate_SEQ-1

Goals: To evaluate whether or not the formation and properties of secondary organic aerosol (SOA) formed via sequential oxidation of a-pinene followed by limonene can be described as linear combinations of pure a-pinene and limonene systems.Summary: 2 uL of liquid a-pinene was injected, followed by the injection of 100 ppb of N2O5 (source of nitrate radical) at a rate of 11.3 ppb / minute. After 60 minutes since the start of N2O5 injection, 0.35 uL of liquid limonene was injected, followed by the additional injection of 40 ppb of N2O5 (source of nitrate radical) at a rate of 11.3 ppb / minute.Organization: Ng Research Group Lab Affiliation: Georgia Institute of Technology Chamber: Georgia Tech Environmental Chamber (Far)Experiment Category: Gas phase chemical reaction, Condensed-phase chemical reaction, Volatility and partitioning, Aerosol formation Oxidant: Nitrate radical Reactants: alpha-Pinene, Limonene Reaction Type: Dark oxidation, Oligomerization Relative Humidity: 0-2 Temperature: 5 Seed Name: Ammonium sulfate
