Methods have been developed for the quantification of low-microgram levels of the extractable organic matter contained in the atmospheric fine aerosol fraction. Extract quantification is accomplished by computer-assisted high-resolution gas chromatography (HRGC) used in conjunction with a procedural recovery mixture containing perdeuterated compounds of differing polarity and molecular weight. Recovery data for these species indicate that relative volatility rather than functional group classification is the primary factor affecting overall recovery. Routine quality control analysis is performed on a per-sample basis by high-resolution gas chromatography/mass spectrometry (HRGC/MS) for confirmation of the standard components and for identification of procedural contaminants. By the way of illustration, fine aerosol samples have been analyzed from Anaheim. California. The absolute solvent extract yields range from 49 to 346μg of organic carbon, and demonstrate a seasonal variation with winter maximum and summer minimum concentrations.
