PMI metal composition analysis, also known as on-site spectral detection, is a non-destructive analysis method that can quickly and accurately determine the types and contents of elements in metal materials. This technology uses high-energy X-rays to irradiate the surface of the sample, exciting the internal electron transitions of the sample atoms to produce secondary X-rays, and then measuring the energy and intensity of the secondary X-rays to determine the type and content of elements in the sample. It has the advantages of fast, accurate, and non-destructive, and is widely used in quality control, scrap metal recycling, and other fields in the manufacturing industry.
