Abstract

Organic compounds are ubiquitous in ambient aerosol and constitute a substantial fraction of total fine particle mass in anthropogenic air. Analytical techniques for measuring organic aerosols (both in terms of compound level and total mass) have not been fully established because organic aerosols consist of hundreds to thousands of chemical species with a very wide range of chemical and thermodynamic properties. This paper reviews some representative methods for the measurements of total mass concentrations of organic carbon (OC) and organic matter (OM) in ambient aerosol. The OC measurements include a thermal-optical reflectance/transmittance method and a particle-into-liquid sampling (PILS) method. The OM measurements include an Aerodyne aerosol mass spectrometer (AMS) and an off-line analysis by gravimetric mass measurements. The advantages and limitations of each method are discussed.
