ICARUS Chamber Experiment: Caltech Atmospheric Chamber_20140802_Methacrylolyl peroxynitrate (MPAN)/ALPHA-PINENE/hydrogen peroxide/Methacrylic acid epoxide (MAE)_Hydroxyl radical_No Seed_Dry
Listed in National Center for Atmospheric Research
Goals: This experiment is a repeat of 140724 experiment but this time with the NO2PAN monitor to quantify NO, PAN, and MPAN.
Description
The goal of this experiment is to photooxidize MPAN and capture NO3 with a-pinene, while observing secondary organic aerosol (SOA) formation through dry nucleation. MAE was added toward the end of the experiment to see if it enhanced SOA formation.
Summary
Read the rest (1 more)
Observations are the same as for 140724 - large SOA formation, alpha pinene was observed to capture NO3 which indicated that NO3 is product of MPAN oxidation, and MAE does not increase or otherwise alter SOA formation Organization: Caltech Atmospheric Chamber Lab Affiliation: California Institute of Technology, Pasadena, CA Chamber: Near/Far Bag 2012-2015 (Tran) Experiment Category: Gas phase chemical reaction, Aerosol formation Oxidant: Hydroxyl radical Reactants: Methacrylolyl peroxynitrate (MPAN), ALPHA-PINENE, hydrogen peroxide, Methacrylic acid epoxide (MAE) Reaction Type: Photooxidation Relative Humidity: 4 Temperature: 15 Pressure: 750 Torr
