ICARUS Chamber Experiment: Nguyen Group_20221205_beta-Pinene/Ammonium Sulfate/Ozone/Hydrogen Peroxide_Ozone_Ammonium sulfate

Goals: To quantify SOA yield and gas-phase product yields from humid ozonolysis of b-pinene, which will serve as a "control" experiment to subtract the ozonolysis contribution to the nighttime chemistry of b-pinene as measured in the experiment on 5/25/22. Summary: The chamber was humidified, after which H2O2, and O3 were injected in the chamber and allowed to equilibrate. Ammonium sulfate seed particles were injected. Then b-pinene was injected and decayed by reaction with ozone (plus some contribution from OH). Particle formation was monitored by SMPS, and RH/T/O3/NOx were monitored throughout. No CIMS during this experiment (see comparable experiment on 5/27/22). O3/NOx data sometimes require post-correction not applied here, including subtraction of an ozone interference from H2O2 (1 ppm H2O2 is detected as about 12 ppb ozone) and correction for an in-line HEPA filter (see timeline for applicable timing) that scrubs about 10% of NO2 and 45% of ozone.
