ISO 15202 Multi-Element Analysis in Steel by ICP
The ISO 15202 standard provides a robust method for the multi-element analysis of steel using Inductively Coupled Plasma (ICP) spectrometry. This technique is particularly valuable for identifying trace elements, impurities, and alloying additions in steel samples.
Steel manufacturing often involves the addition of specific elements to achieve desired mechanical properties or improve corrosion resistance. The ISO 15202 method ensures precise quantification of these elements, including chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), and other trace metals like vanadium (V) and molybdenum (Mo). By adhering to this standard, laboratories can deliver reliable results that meet international quality benchmarks.
ICP analysis is preferred for its high sensitivity and accuracy. It allows the detection of elements at very low concentrations, making it ideal for identifying trace impurities or minor alloy additions. The method involves exciting atoms within a plasma discharge chamber to produce characteristic emissions, which are then measured by the spectrometer. This process ensures consistent results across different laboratories.
Preparation of specimens is critical for accurate analysis. Samples must be prepared according to ISO 15202 specifications, ensuring proper digestion and dissolution techniques to release all target elements into a solution suitable for ICP measurement. The choice of acid mixtures in this process can significantly influence the final results.
Instrumentation plays a crucial role in achieving accurate measurements. High-performance ICP-MS (Inductively Coupled Plasma Mass Spectrometry) systems are recommended to ensure the precision and sensitivity required by ISO 15202 standards. These instruments typically include a nebulizer, peristaltic pump, spray chamber, plasma torch, and mass spectrometer.
Once analyzed, data is processed through software that calculates elemental concentrations based on calibration curves prepared using certified reference materials (CRMs). The results are then reported according to ISO 15202 guidelines, providing a clear and concise summary of the chemical composition of the steel sample.
