ICARUS Chamber Experiment: Nguyen Group_20220602_Limonene/Ammonium Sulfate/Ozone/Hydrogen Peroxide_Ozone_Ammonium sulfate

Goals: To quantify SOA yield and gas-phase product yields from humid ozonolysis of limonene, which will serve as a "control" experiment to subtract the ozonolysis contribution to the nighttime chemistry of limonene as measured in the experiment on 6/1/22.

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 limonene was injected and decayed by reaction with ozone (plus some contribution from OH). Gas phase organics were monitored by CF3O- CIMS (units: normalized counts), particle formation was monitored by SMPS, and RH/T/O3/NOx were monitored throughout.

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.
