| Abstract |
Secondary ion mass spectrometry is evaluated for application to the determination of the composition and structure of individual particles. Analyses of many elemental constituents at the ppm level can be obtained in individual particles as small as micrometers in diameter. Molecular signals, both organic and inorganic, can be detected from particles above 20 micrometers in diameter. Quantitative analyses of elemental constituents can be made with a relative accuracy of 25 percent by means of empirical relative sensitivity factors and within a factor of two by means of a physical model. Multielement depth profiles can be obtained from individual particles as small as 4 micrometers in diameter. Depth profiles of individual particles from SRM 1648 Urban Air Particulate reveal pronounced surface concentrations of lead and barium. Implementation of SIMS depth profiling requires automation to make use of the full spectral information and to eliminate matrix effects by normalization. |
