GB/T 16481-1996 gives the standard spectrum table of rare earth elements microwave plasma torch emission Light spectrum (MPT-AES). It covers the characteristic emission Light spectrum data of various rare earth elements under MPT-AES, and records the wavelength, intensity and other key information of each element spectral line in detail. These standard spectra provide an important comparison reference for the analysis of rare earth elements using MPT-AES technology, which is convenient for scientific researchers and inspectors to accurately identify and determine the types and contents of rare earth elements. In the fields of rare earth resource exploration, rare earth material research and development, and mass testing of related products, it helps to achieve efficient and accurate analysis work.
