Description
Basic principle of XRF analysis
The electron orbital potential energy of the various elements is different from each other excitation is different from each other,i.e.,each element emits x-rays with the specific energy of the atom of that element,which represents the characteristics of the element and is therefore called the characteristic X-ray of the element. The characteristic X-ray of each element has its specific energy, and the X-ray detected with certain energy can determine the existence of this element in the material sample.
