An XRF Spectrometer (X-ray Fluorescence Spectrometer) is an analytical instrument used for non-destructive elemental analysis of various materials. Its working principle is based on the interaction between X-rays and the atoms within a sample. The process involves the following steps:
X-ray Excitation: A high-energy primary X-ray beam, generated by an X-ray tube (e.g., 50W micro-focused tungsten or beryllium window), is directed towards the sample.
Photoelectric Effect: When these primary X-rays strike sample atoms, they eject inner-shell electrons, creating unstable vacancies.
Fluorescence Emission: To regain stability, outer-shell electrons fill these vacancies, releasing energy as secondary, characteristic fluorescent X-rays. Each element emits X-rays at unique energy levels, acting as its "fingerprint".
Detection and Measurement: A highly sensitive detector (such as a Si-Pin or SDD detector) captures these fluorescent X-rays, measuring both their distinct energies and intensity.
Data Analysis: An integrated computer system with specialized software processes these signals. By analyzing the unique energy signatures, the software identifies the elements present and quantifies their concentration based on X-ray intensity.
Result Display: The final elemental composition and concentration data are then presented to the user, typically on a screen. This entire process is non-destructive, rapid, and precise.
