Characterization of Particulate Matter using the GS-MS Organic Aerosol Monitor


Measuring and characterizing particulate matter (PM) in the atmosphere is challenging due to the large variety in particle types and the volatile nature of the compounds found in aerosols.  The GC-MS Organic Aerosol Monitor (OAM) is a new instrument developed at BYU that collects PM and identifies key organic molecules found in these particles. The instrument uses filter collection/thermal absorption and GC-MS techniques to measure the concentration of particle phase organic compounds on an hourly averaged basis. This instrument has been field tested in Provo, West Valley, and Lindon, UT. Various organic compounds, such as levoglucosan, polycyclic aromatic hydrocarbons (PAHs), dehydroabietic acid, and stearic acid have been detected and hourly averaged concentrations recorded.  Future work includes expanding the capabilities of the OAM to measure gas phase and volatile organic compounds.
