摘要
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 than 1 ppm. Comparison of determined and listed elemental concentration values for five reference materials is given.
