AUTOMATED ELEMENTAL ANALYSIS USING ENERGY DISPERSIVE X-RAY FLUORESCENCE ANALYSIS
The application of energy dispersive x-ray fluorescence analysis to the measurements of air particulate samples has been described in several recent publications. Among its many advantages, the possibility of automatic analysis for large scale monitoring programs has not been widely discussed. We describe the completion of a program in which a total of 34,000 air particulate samples have been collected and analyzed over the past two years. An automatic photon-excited energy dispersive spectrometer was used to obtain elemental concentrations for 27 elements on each sample. The sensitivity of the system is adequate to detect quantities of 10 ngm/cm{sup 2} or less in a measurement time of approximately six minutes per sample. The precision and accuracy of the results will be compared to statistical analyses of the data set. Summaries of the results are presented and the implications for air particulate monitoring discussed.
