ICARUS Chamber Experiment: Hildebrandt Ruiz Lab_20151231_ISOPRENE_Chlorine radical_Ammonium sulfate_C5_continuous Cl injection_neutral seed

Goals: To calculate SOA yield from Cl-initiated photooxidation of isoprene at a VOC:Cl2 ratio of 0.61, and using neutral seed. Cl was continuously injected throughout the lights-on period with the total injected concentration reaching 120 ppb.Summary: Neutral seed was injected (initial seed surface area unknown since SEMS was out of order), followed by a Cl2 injection out of a gas cylinder, and the isoprene injection using a heated glass bulb. Temperature was kept at 25C for the whole duration of the experiment, while RH was kept at less than 10%.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: ISOPRENE Reaction Type: Photooxidation Temperature: 25 Seed Name: Ammonium sulfate
