X-ray source: The X-ray source generates a high-energy X-ray beam that is directed at the sample.
Sample: The sample is placed in the analyzer’s sample chamber.
Detector: The detector measures the energy of the secondary X-rays emitted by the sample.
How Does an XRF Jewelry Tester Work
The XRF analysis process is relatively straightforward:
X-ray Excitation
The XRF gold analyzer begins by emitting a high-energy X-ray beam onto the surface of the gold sample. This X-ray excitation prompts inner-shell electrons in the atoms of the sample to become temporarily displaced.
Emission of Fluorescent X-rays
As the displaced electrons return to their original positions, they emit fluorescent X-rays. The energy levels of these emitted X-rays are characteristic of the specific elements present in the sample.
Energy Dispersive Detection
The XRF analyzer employs an energy dispersive detector to measure the energy levels of the emitted X-rays. This information is then processed to identify the elemental composition of the gold sample.
Quantification and Analysis
By comparing the energy levels of the emitted X-rays to known standards, the XRF analyzer quantifies the concentration of different elements in the gold sample. This includes not only gold but also other potential alloying elements.
