Applications of X-ray Fluorescence Spectrometry in Elemental Analysis of Crystals

The applications of X-ray fluorescence spectrometry in elemental analysis of crystals were reviewed. Although it is an effective and efficient approach for elemental analysis, X-ray fluorescence analyses require different sample preparation methods depending on different sample types and require calibration standards to correct matrix effects. Abnormal reflection may lead to complicated background and confused qualitative interpretation or/and quantitative measuring conditions if the measured specimen is a single crystal. In this case, the fusion method is preferable. Attention must be paid to the uncertainty of the measurement when the results are employed to a specific purpose.
