Title:

ICARUS Chamber Experiment: Nguyen Group_20210419_2-methylbut-3-ene-1,2-diol/OZONE_Ozone_Ammonium sulfate


Description:

Goals:
Oxidation product & SOA formation study on 2-methylbut-3-ene-1,2-diol (1,2-DHI) ozonolysis under humid (50% RH) conditions.

Summary:
1,2-DHI and ammonium sulfate seed aerosol were injected into a humidified chamber and the bag was mixed and allowed to equilibrate. Ozone was injected over the course of 2 minutes with pulses of mixing air. Ozonolysis and SOA formation were allowed to continue for ~5.5 hours before shutdown. At ~4:15pm an MSMS scan of m/z 169 was performed to help identify this product.
