Chemical composition testing using the PMI (Positive Material Identification) spectrometry method is an essential part of quality control for metallic alloys. This non-destructive method provides both qualitative and quantitative composition analysis, accurately determining the concentration of individual chemical elements. The analysis enables precise alloy grade identification and verifies material compliance with technical specifications or manufacturing standards.
PMI spectrometry is based on analyzing the unique electromagnetic spectrum emitted by the chemical elements within a material sample. Depending on the applied technology, different spectrometric methods may be used, such as X-ray fluorescence analysis, optical emission analysis, or laser-induced breakdown spectroscopy. The measurement results are presented as the percentage breakdown of individual elements.
PMI testing is essential across a wide range of industries and assets, including industrial installations, energy sector installations, pipelines, and tanks. It is also criticalfor identifying structural materials and components in the aerospace industry, as well as inspecting raw materials and finished products. The PMI method is particularly valuable when rapid, in-situ material identification is required without the need for sampling or laboratory analysis.
