ICARUS Chamber Experiment: Nguyen Group_20190726_ALPHA-PINENE/OZONE_Ozone_Ammonium sulfate_control_for_20190725

Goals: Control (no NO2) for 20190725, which itself is a control experiment for the O3+NO2+H2O2 series -- this one with no H2O2, and therefore likely very little HO2 formation during oxidation (more RO2 + RO2, some RO2 + NO3 likely)Summary: O3 was injected in the chamber followed by ammonium sulfate seed particles. Then a-pinene was injected and decayed by simultaneous reaction with ozone and NO3. 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 airExperiment Category: Gas phase chemical reaction, Aerosol formation Oxidant: Ozone Reactants: ALPHA-PINENE, OZONE Reaction Type: Dark oxidation Relative Humidity: 5 Temperature: 22 Seed Name: Ammonium sulfate Pressure: 755 Torr
