Goals:
To calculate SOA yield from Cl-initiated photo-oxidation of isoprene at a VOC:Cl2 ratio of 0.60, and using neutral seed.
Summary:
Neutral seed was injected with an initial seed surface area of 1500 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%. H2SO4 was injected halfway through the lights-on period (at 14:52).
