Gas/Particle Partitioning of Organic Acids: Instrument development and field deployment
Organic acids are common atmospheric oxidation products and can help our understanding of those mechanisms. In particular their partitioning between the gas and particle phase can lead to a better understanding of their contribution to SOA loadings and lifetime. In this talk I will be presenting the development a new instrument (the FIGAERO-HRToF-CIMS) for real time detection of both gas and particle phase organic acids. Results from lab characterization and a field campaign as part of the Southern Oxidant and Aerosol Study (SOAS) will be shown.
