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.详细>
