Since 1980 a number of Standard Reference Materials (SRM's) have been issued by the National Bureau of Standards (NBS) to assist in validating measurements for the determination of polycyclic aromatic hydrocarbons (PAH) and other polycyclic aromatic compounds (PAC). These SRM's are certified for selected PAC and range in analytical difficulty from calibration solutions to complex natural matrix materials, such as air and diesel particulate matter, shale oil, and crude oil. In the past year three new SRM's have been introduced: (1) SRM 1647a 'Priority Pollutant PAH in Acetonitrile', (2) SRM 1491 'Aromatic Hydrocarbons in Hexane/Toluene', and SRM 1597 'Complex Mixture of PAH from Coal Tar'. The SRM's available from NBS for use in the determination of PAC are described and the concentrations of PAC determined in the natural matrix SRM's are summarized and compared. The primary analytical techniques used for the measurement of PAC in these SRM's were gas chromatography, liquid chromatography, and gas chromatography/mass spectrometry. [ABSTRACT FROM AUTHOR] |
