Title:

ICARUS Chamber Experiment: Nguyen Group_20190911_ALPHA-PINENE/OZONE/hydrogen peroxide_Ozone_Ammonium sulfate_control_for_20190910


Description:

Goals:
Part of a series to quantify the nitrooxy-hydroperoxide yield and the SOA yield from nighttime RO2+HO2-dominated NO3-initiated chemistry of a-pinene by adding H2O2 + ozone + NO2 to the chamber. This experiment serves as the "no-NO2" control for the experiment on 20190910, to see what the ozonolysis products are so those can be subtracted off the NO3+ozonolysis results.

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.
