The Content Matching Function

When using devices such as X-ray fluorescence spectrometers for process and qualitymanagement, the aim is to ascertain whether the analyzed values are within the parameters set bystandards (such as JIS). A new matching function that identifies the steel type has been added tothe EDX-700/800 separate to the function which determines whether standards are being met. Thisfunction selects a type of steel with a high degree of similarity (for example SUS304) from a storedlibrary. It incorporates two methods, the conventional method of spectral matching by comparisonof the X-ray intensity, and the content matching method, which works by comparing quantitativevalues. Shimadzu has been the first to install the latter method in an X-ray fluorescencespectrometer, and enables it to be used not just with finished products but with acceptancematerials and waste materials. Examples of use particularly suited to this content matchingfunction, stainless steel, and aluminum alloys are introduced below.
