ICARUS Chamber Experiment: Hildebrandt Ruiz Lab_20150706_ISOPRENE_Chlorine radical_Ammonium sulfate_C1_continuous Cl injection_neutral seed

Goals:
To calculate SOA yield from Cl-initiated photo-oxidation of isoprene at a VOC:Cl2 ratio of 0.42, and using neutral seed. Cl was continuously injected throughout the lights-on period with the total injected concentration reaching 94 ppb.

Summary:
Neutral seed was injected with an initial seed surface area of 950 um2/cm3, 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%.
