| Elemental composition analysis can be used to determine the elemental composition of metal materials and the elemental ratios of glass and ceramic materials, as well as the proportion of metallic additives in polymers. Elemental analysis is one of the most common analytical methods used in general material analysis. – Elemental analysis of metal materials can be used to verify whether the material grade is correct (PMI) and determine whether the composition ratios are within an acceptable range. Many metal materials differ only in their carbon (C) content, such as high-carbon steel, medium-carbon steel, and low-carbon steel. Carbon equivalent (C) may also be required for welding applications. Certain elements are commonly present but are difficult to detect due to limitations of the analytical tools, making them difficult to identify. Ex. Boron (Be) – Ceramic materials can be identified by their elemental ratios. Elemental composition affects strength, electrical properties, magnetic properties, physical properties, and more. – The elemental ratios in polymers may indicate whether certain elements have been intentionally added, such as platinum (Pt) cross-linking or sulfur (S) cross-linking, or whether hazardous substances such as Pb and Cd have been avoided. – Elemental analysis tools include XRF (X-ray Fluorescence), LIBS (Laser-Induced Breakdown Spectroscopy), AA (Atomic Absorption Spectroscopy), ICP (Inductively Coupled Plasma), ICP-MS (Inductively Coupled Plasma Mass Spectrometry), EA (Elemental Analyzer), Spark (Spark Testing)… The appropriate analytical tool can be selected according to the application requirements and the required testing concentration. |
