Determination of trace elements in organic specimens by energy-dispersive x-ray fluorescence using a fundamental parameters method
(Wiley Analytical Science, 1991)
A rapid method for the simultaneous determination of trace elements in milk powder by energy-dispersive x-ray fluorescence has been developed. The measurement system consists of an Si(Li) detector, an x-ray tube coupled ...
Radioisotope X-ray fluorescence analysis of vanadium in petroleum coke samples
(Journal of Radioanalytical and Nuclear Chemistry, 1990)
Radioisotope X-ray fluorescence spectrometry, RIXRF, was used for the determination of vanadium in Venezuelan petroleum coke samples using a simple standardless method and fundamental parameter approach. The values obtained ...
Trace element determination of mercury by total-reflection X-ray fluorescence
(Spectrochimica Acta Part B: Atomic Spectroscopy, 1997-07-01)
A rapid and simple method is presented for the determination of trace amounts of ionic mercury in solutions by total-reflection X-ray fluorescence. The method relies on the formation of a mercury amalgam on a 50 nm thick ...
