Description:
Goals:
To calculate SOA yield from Cl-initiated photooxidation of isoprene at a VOC:Cl2 ratio of 0.45, and using neutral seed.
Summary:
Neutral seed was injected with an initial seed surface area of 900 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%.

Description:
Goals:
To quantify gas-phase product yields and the SOA yield from nighttime RO2+RO2- and RO2+NO3-dominated NO3-initiated chemistry of a-pinene using N2O5.
Summary:
a-pinene and seed aerosol were injected into the chamber and allowed to mix, followed by N2O5, which quickly dissociated to NO2 and NO3. a-pinene decayed rapidly by reaction with NO3. Gas phase was monitored by CF3O- CIMS and particle formation by SMPS. After all injections, a DNPH cartridge was collected for offline HRMS analysis.
