Energy Dispersive X-Ray Fluorescence Spectrometry Using Pulsed X-Ray Excitation

Determining the Content of Silicon Dioxide in Bauxites Using X-Ray Fluorescence Spectrometry

The X-ray fluorescence spectrometry and the MA.BM.006 reference spectrophotometric methods were used to determine the content of SiO2 (%) in bauxites from different deposits. The treatment of samples prior to the analysis involved the following steps: annealing, melting using the borax method,  and the formation of beads. Certified reference bauxite samples were used for the cali...

Analysis of the elemental concentrations in rat femur's head using energy dispersive X ray fluorescence spectrometry

EDXRF spectrometry is used normally to determine the concentration of the different elements in a sample with advantages of good sensitivity, multielemental capabilities, fast, non-destructive and because of this simple relation to the fundamental physics of atom-radiation interaction, make of EDXRF a highly attractive analytical technique. A major goal for research in biomedical sciences over ...

Simultaneous determination of trace elements in serum by energy-dispersive x-ray fluorescence spectrometry.

Energy-dispersive x-ray fluorescence is applied in the analysis of human serum to determine the concentrations of several elements simultaneously with minimal manipulation of the sample. The analytical procedure has been developed with standard sera, and standardization, detection limits, and reproducibility have been established. A 50-microL sample of diluted serum, to which an internal standa...

Quantification in X-Ray Fluorescence Spectrometry

X-ray Absorption Spectroscopy Using X–ray Fluorescence Spectrometer

Strong characteristic Kα X-ray lines are accompanied by weak lines due to the radiative Auger effect (RAE) [1, 2]. The characteristic Kα fluorescent X-rays (K-L2,3 lines) are emitted by the 2p→1s electric dipole transition after one of the 1s electron photoionization, Though the probability is less than 0.01, one of the 2p electrons is excited into an unoccupied discrete or continuum level simu...
