ICARUS Chamber Experiment: Nguyen Group_20190624_ALPHA-PINENE/OZONE/hydrogen peroxide_Ozone_Ammonium sulfate_control_for_20190620

Goals: Control experiment to quantify the SOA yield from a-pinene ozonolysis to subtract off from the corresponding experiment with NO2 (20190620) so that we can quantify just the a-pinene+NO3 contribution. Part of a series of varying initial seed particle surface area to see how that affects SOA formation. Summary: H2O2 and O3 were injected in the chamber and allowed to equilibrate. Ammonium sulfate seed particles were injected. Then a-pinene was injected and decayed by reaction with ozone. Gas phase was monitored by CF3O- CIMS and particle formation by SMPS. A filter was collected for later offline analysis. Organization: Nguyen Group Lab Affiliation: UC Davis Chamber: Tran's big bag of air Experiment Category: Gas phase chemical reaction, Aerosol formation Oxidant: Ozone Reactants: ALPHA-PINENE, OZONE, hydrogen peroxide Reaction Type: Dark oxidation Relative Humidity: 5 Temperature: 22 Seed Name: Ammonium sulfate Pressure: 755 Torr
