ICARUS Chamber Experiment: 2014 FIXCIT Study_20140116_ALPHA-PINENE/Methyl nitrite_Hydroxyl radical_No Seed_Alpha-pinene + OH "slow chemistry", dry, 40C, no seeds
d789010
<p>Goals:<br/> Investigate "slow" (isomerization-favoring) OH chemistry of alpha-pinene</p> <p>Summary:<br/> Timeline (UTC, hours):<br/> 00:00, Instruments (NO; CF3O-; GTHOS; OHR; AMS; PTRMS) start sampling the bag<br/> 00:30, Instruments stopped sampling; added CH3ONO to the bag with 5 SLM zero air<br/> 00:35, Added alpha-pinene with 6 SLM zero air in 50degC water bath<br/> 01:22, Stopped alpha-pinene addition<br/> 01:30, Certain instruments started sampling (CF3O- CIMS; GTHOS; NO). GTHOS and NO off bag overnight<br/> 02:05, 2 UV bulbs on (~1% lights)<br/> 16:05, Instruments started sampling on bag; AMS saw nucleation overnight; O3 instrument reads 10 ppbv<br/> 16:30, Lights off<br/> 17:34, Lights on (20%)<br/> 18:15, Lights on (100%)<br/> 19:37, Lights off<br/> 20:20, Add 2 minutes of NO flow to kill O3/HO2<br/> 22:45, Stopped sampling; start flushing</p> <p>Organization: 2014 FIXCIT Study<br/> Lab Affiliation: California Institute of Technology<br/> Chamber: Seinfeld chambers</p> <p>Experiment Category: Gas phase chemical reaction<br/> Oxidant: Hydroxyl radical<br/> Reactants: ALPHA-PINENE, Methyl nitrite<br/> Reaction Type: Photooxidation<br/> Relative Humidity: 5<br/> Temperature: 40<br/> Pressure: 750 Torr</p>
