The application of Raman spectroscopy to the molecular characterization of individual particles from stationary sources is described. The NBS-developed Raman microprobe has been used to characterize microparticles of oil- and coal-fired power plant emissions and boiler samples collected and described by the Environmental Protection Agency. The samples were examined on an 'as received' basis and the results reported do not take into account any sample modifications that may have occurred during sample collection. Raman microprobe analyses of a number of dense agglomerations of largely submicrometer particles, from a sample collected by the EPA and described as coal fly ash, show no Raman spectral features to indicate a glassy material when the particles are first exposed to laser excitation.
