The research and development of materials based on rare earth metals is in demand and promising for the development of microelectronics, optical communications, laser technologies, etc. An important requirement for their effective use is the chemical purity and predictable composition of the raw materials. Establishing the purity of initial REMs and their compounds, control of the composition of intermediate and final products is a complex analytical problem. As a result of research in this work, complex methods have been created for the analysis of magnetic, luminophore and optical materials and raw materials for their preparation using of inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS) and arc atomic emission analysis (AAEA). A complex complementary application of these methods is proposed, which makes it possible to ensure high accuracy and reliability of the results, to expand the determination limits for target impurities, the list of analytes and the range of analyzed materials.
