ICP测定高钢中的Co\Ni\Cr\Ti\Mn\Si\Al\V\Cu\Mo

The analysis of steel is important not only for manufacturers but also for the large number of steel consumers in the engineering and metallurgical industries. The information from an analysis is useful for various purposes, such as the inspection of raw materials, intermediate product and end product; environmental assessment in the factory; process control in iron and steel manufacturing; quality control and product research. However, most of the routine analyses involve Spark Emission Spectroscopy or occasionally X-Ray Fluorescence. With these techniques, the analytical signal is highly dependent on the matrix composition, and precise matching of sample and standard matrices is required for accurate results. However, such techniques lack the detection limit sometimes required. Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) is a well established analytical technique which offers better detection limits for trace element analysis, large linear dynamic range, high precision, good accuracy, and relative freedom from chemical interferences. It can be automated for high speed multi-element analysis of major and minor elements in high alloy steel.
