Title:

ICARUS Chamber Experiment: Nguyen Group_20210114_2-Methylbut-3-ene-1,2-diol/Hydrogen Peroxide_Hydroxyl radical_Ammonium sulfate


Description:

Goals:
Product and SOA formation study on 2-methylbut-3-ene-1,2-diol (1,2-DHI) + OH, using wet (deliquesced) ammonium sulfate seeds at 50% RH. RO2 + HO2 pathway targeted.

Summary:
1,2-DHI and H2O2 were injected, AS solution was atomized, and lights were turned on to initiate photooxidation. The CIMS died briefly partway through; it was only off for ~10 minutes but the signals appear to have changed a bit after restart. Note that the NOx and O3 monitors were sampling the room, not the chamber, until 11:00.
