Analysis of standard metal alloys
Every industry in the United States regulates production and manufacturing of goods for quality and accuracy. One way to regulate an industrial process is through a Quality Control (QC) Quantitative Calibration with a WDXRF (wavelength dispersive X-ray fluorescence) spectrometer, such as the Rigaku ZSX Primus II spectrometer.
A WDXRF quantitative calibration consists of a precisely measured analytical method that is optimized for the material being analyzed with a variety of reference standards. When reference materials are not available to set up a Quantitative Calibration method, the Rigaku ZSX software offers a Semi-Quantitative (SQX ) or standardless quantitative evaluation that can be used for QC and differentiation of product types.
The following table shows data collected on three different certified reference materials using the Rigaku Primus II. B.S. T-22 is titanium alloy standard. Ult1233 (64B) is a cobalt alloy standard. Inco 690 (201A) is a nickel alloy standard.

Table 1: Analyzed Brammer metal alloy standards
As the data shows, quality materials characterization can be done via the Rigaku SQX software on a wide range of metallic alloy blends. The Rigaku SQX software is an excellent screening tool for the analysis of a wide variety of materials, when there is a lack of certified reference materials to generate a Quantitative Calibration for industrial quality control.
