Title:

ICARUS Chamber Experiment: Nguyen Group_20190718_ALPHA-PINENE/OZONE/10102-44-0_Nitrate radical_Ammonium sulfate_noH2O2


Description:

Goals:
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:
NO2 and O3 were injected in the chamber and allowed to equilibrate, forming NO3 (and some N2O5). Ammonium sulfate seed particles were injected. 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.
