Quantitative chemical analysis is performed to accurately determine the concentration of elements in the material comprising a given sample. A variety of analysis techniques are used for metals and alloys to determine the alloy composition of raw materials to verify conformance to a specification or to identify the alloy used to make a specific component. Quantitative chemical analysis methods are also used occasionally for evaluation of foreign material contaminants in special cases for failure analysis or investigation of product manufacturing or handling problems (mee-inc.com).
Quantitative chemical analysis may be performed by one or more complimentary techniques, commonly including spark optical emission spectroscopy (Spark OES), inductively coupled plasma spectroscopy optical emission spectroscopy (ICP OES), x ray fluorescence spectroscopy (XRF), wet chemical analyses, combustion methods, and inert gas fusion(IG).The specific technique chosen will depend on the type of sample, quantity of material available for analysis, desired result, and cost constraints. In most cases, the applicable analysis techniques can detect parts per million concentrations or better (mee-inc.com).
