Analysis of rocks

This Application Note shows the analysis three rock Reference Materials from Rocklabs, Ltd., using Rigaku RPF-SQX fundamental parameters. Performance is shown for both hydraulically pressed pellets and loose powders.



Elemental analysis is important in the analysis of rocks and ores, from screening at the quarry site or mine, throughout the processing areas to final analysis. Majors and minors are important during processing, to ensure proper extraction and process control. Trace elemental analysis, especially of precious metals, is also extremely important to ensure the value of the processing is optimized. Along the entire processing line, a fast and simple technique is required without the need for large suites of assayed calibration standards to match each matrix type. To meet these industry challenges, Rigaku offers the NEX CG EDXRF elemental analyzer. The NEX CG, using indirect excitation and polarization, offers the non-technical operator a powerful and simple tool for the measurement of the elements sodium through uranium in rocks and ores, while retaining the power and versatility for the XRF expert involved in rock and ore analysis.

NEX CGRigaku NEX CG delivers rapid qualitative and quantitative determination of major and minor atomic elements in a wide variety of sample types — with minimal standards. Unlike conventional EDXRF analyzers, the NEX CG was engineered with a unique close-coupled Cartesian Geometry (CG) optical kernel that dramatically increases signal-to-noise.
