Trace element determination using synchrotron radiation
The use of synchrotron radiation for high sensitivity trace multielement X-ray fluorescence determinations is demonstrated. Experimental conditions that yield optimum sensitivity are described. Emphasis was placed on establishing calibration techniques and procedures that would yield accurate results with high precision for elements present at concentration levels less that 1 ppm. Comparison of determined and listed elemental concentration values for five reference materials is given. By use of optimum conditions, minimum detectable limits of 20 ppb were ascertained for most elements. The results clearly illustrate the feasibility of performing high sensitivity trace element determinations for extremely small samples. 11 references, 7 figures, 2 tables.
