ICARUS Chamber Experiment: Hildebrandt Ruiz Lab_20180108_DODECANE/nitric oxide/nitrite_Chlorine radical_Ammonium sulfate_dry

Goals: Find SOA yield for dodecane + Cl under high NOx condition (NO and NO2 injected) and low RH. Investigate volatility behavior based on 2D thermograms.Summary: 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. 126.4 ug/m^3 of SOA was formed, giving a mass yield of 1.40. This is Experiment #11 in associated publication.Organization: Hildebrandt Ruiz Lab Lab Affiliation: University of Texas at Austin, Austin, TX, USA Chamber: LHR ChamberExperiment Category: Gas phase chemical reaction, Volatility and partitioning, Aerosol formation Oxidant: Chlorine radical Reactants: DODECANE, nitric oxide, nitrite Reaction Type: Photooxidation Temperature: 25 Seed Name: Ammonium sulfate
