ICARUS Chamber Experiment: 2014 FIXCIT Study_20140117_4-hydroxy 3-peroxy ISOPOOH_Hydroxyl radical_No Seed_4,3-ISOPOOH + OH, low NO, dry, no seeds

Goals:
Observe the products (first generation:beta IEPOX) of OH oxidation; evaluate the OH LIF interference from an organic peroxide; observe ISOPOOH and its oxidation products as interferences for GC-FID/PTR-MS/others.

Summary:
The experiment went well. Long sampling periods were provided before and after oxidation to help instrument teams evaluate interferences from ISOPOOH and its products. A little over 2/3 of the ISOPOOH was reacted away using ~500 ppb of H2O2 as the OH source. Note that the ISOPOOH sample itself contained H2O2, so H2O2 was present in the bag before it was added explicitly.
