XRF technique
How does XRF work? How does XRF inspection work?
XRF spectrometer, also known as X-ray Fluorescence Spectrometer. An elemental composition of solid or liquid samples is measured non-destructively using this method. Figure (1) illustrates the method of generating X-rays within an instrument and irradiating a sample to be tested, and Figure (2) illustrates the process of knocking out electrons in the sample's inner orbital region using this method.
By filling the vacancies in the inner layer with electrons at a higher energy level, the energy released by them is released in the form of radiation, which is called X-ray Fluorescence. Different elements emit their own characteristic X-rays, which have different wavelengths and energies after being excited. The X-rays are then received by the analysis instrument and converted into the corresponding, spectral signals for analysis technology, referred to as XRF, as shown in (3).
