Wheeler, B D; Jacobus, N C

The major ash forming constituents of whole coal and ultimately potential ash content can be performed by energy dispersive x-ray fluorescence in approximately 200 seconds. Complete quantitative analysis including the trace elements would consume approximately 800 seconds. Accuracies approaching a tenth of one percent absolute can be achieved in the analysis of the major elements, but require interelement corrections either for absorption/enhancement effects or spectral overlaps. Two hundred second minimum detectable concentrations range from approximately one part per million for elements near arsenic to about one tenth of one percent for sodium. The validity of the method based on the listed standards was tested by analyzing NBS 1632A as an unknown. 10 figures, 7 tables.
