ICARUS Chamber Experiment: Hildebrandt Ruiz Lab_20180322_DECANE/nitrite_Chlorine radical_Ammonium sulfate_dry

Goals: Find SOA yield for decane + Cl under high NOx condition (NO2 injected). Investigate volatility behavior based on 2D thermograms.Summary: Ammonium sulfate seed (0.01M, 150 mL) was injected using an aerosol generation system. Cl2 gas and NO2 gas were injected from their cylinders. 81 ug/m^3 of decane was injected into a glass bulb and heated clean air was made to flow over it, carrying the volatilized decane into the chamber. After ~30 minutes (sufficient mixing time), lights were turned on for 1 hour (12:08:45-13:09:06). 43.1 ug/m^3 of SOA was formed, giving a mass yield of 0.45. This is Experiment #6 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: DECANE, nitrite Reaction Type: Photooxidation Temperature: 25 Seed Name: Ammonium sulfate
