ICARUS Chamber Experiment: Hildebrandt Ruiz Lab_20180117_DODECANE/nitric oxide/nitrite_Chlorine radical_Ammonium sulfate_high RH

Ammonium sulfate seed (0.01M, 150 mL) was injected using an aerosol generation system. Cl2 gas, NO and NO2 gas were injected from their cylinders. 90 ug/m^3 of dodecane was injected into a glass bulb and heated clean air was made to flow over it, carrying the volatilized dodecane into the chamber. After ~30 minutes (sufficient mixing time), lights were turned on for 1 hour. 98.9 ug/m^3 of SOA was formed, giving a mass yield of 1.10.
