ICARUS Chamber Experiment: 2014 FIXCIT Study_20140111_nitric oxide/ALPHA-PINENE/hydrogen peroxide_Hydroxyl radical_No Seed_Alpha-pinene + OH, high NO, dry, (NH4)2SO4 seed at end

Goals: High NO oxidation of alpha-pinene to test products. Interested mainly in: organic nitrate yield from alpha-pinene at the high NO limit -products formed in high NO oxidation of alpha-pinene to confirm for CIMS instruments what potential products formed in SOAS -potential contribution of alpha-pinene derived nitrates to particle phase nitrates seen at SOAS. Secondary goals: potential effect of addition of seed aerosol on apparent loss rate of gas-phase compounds

Summary: The initial measurements of alpha -pinene and alkyl nitrates appeared to go well for PTR-MS and TD-LIF. Ozone began creeping up about ~30min into the experiment, reaching a maximum <90ppbv O3. NO was injected in after about an hour and 15 minutes after lights on to titrate out the ozone. Particle nucleation was observed roughly ~1hr 15min into the oxidation, potentially from an OH spike from the NO injection due to PNA buildup. After 08 ~5hrs of oxidation, the lights were turned off. Thirty minutes of dark sampling followed, at which point ammonium sulfate seed was injected into the chamber to determine what effect, if any, this will have on wall-loss of various species.
