ICARUS Chamber Experiment: 2014 FIXCIT Study_20140116_ALPHA-PINENE/Methyl nitrite_Hydroxyl radical_No Seed_Alpha-pinene + OH "slow chemistry", dry, 40C, no seeds

Goals:
Investigate "slow" (isomerization-favoring) OH chemistry of alpha-pinene

Summary:
Timeline (UTC, hours):
00:00, Instruments (NO; CF3O-; GTHOS; OHR; AMS; PTRMS) start sampling the bag
00:30, Instruments stopped sampling; added CH3ONO to the bag with 5 SLM zero air
00:35, Added alpha-pinene with 6 SLM zero air in 50degC water bath
01:22, Stopped alpha-pinene addition
01:30, Certain instruments started sampling (CF3O- CIMS; GTHOS; NO). GTHOS and NO off bag overnight
02:05, 2 UV bulbs on (~1% lights)
16:05, Instruments started sampling on bag; AMS saw nucleation overnight; O3 instrument reads 10 ppbv
16:30, Lights off
17:34, Lights on (20%)
18:15, Lights on (100%)
19:37, Lights off
20:20, Add 2 minutes of NO flow to kill O3/HO2
22:45, Stopped sampling; start flushing
