Technology

Energy dispersive X-ray fluorescence (EDXRF) is a routinely used analytical technique for the qualitative and quantitative determina­tion of major and minor atomic elements in a wide variety of sample types. The heart of its versatility stems from the ability to provide rapid, non-destructive, multi-element analyses—from low parts-per-million (ppm) levels to high weight percent (wt%) concentrations—for elements from sodium (11Na) to uranium (92U).

X-ray Transmission (XRT) on-line process analyzers are routinely employed to classify crude oil and marine bunker fuels that contain 0.02-6 wt% sulfur (S). In this method, sulfur absorbs X-rays transmitted between an X-ray source and detector. The technique is well suited to the high pressures and extreme temperatures employed in transmission pipelines and blending operations.
   

Mining and Refining

Rapid Elemental Analysis of Ores, Feeds, Slags, or Tailings



 

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash.

Whether the determination entails measurement of ores, feed, slags, or tailings in the mining process, Energy Dispersive X-ray Fluorescence (EDXRF) spectroscopy is one of the most commonly employed technique for these routine determinations of metal bearing minerals as well as metals and their oxides.

Minimized standards with RPF-SQX analytical software

The Rigaku NEX CG EDXRF is powered by a new qualitative and quantitative analytical software, RPF-SQX, that features Rigaku Profile Fitting (RPF) technology. The software allows semi-quantitative analysis of almost all sample types without standards - and rigorous quantitative analysis with a few standards. Featuring Rigaku's famous Scatter FP method, the software can automatically estimate the concentration of unobserved low atomic number elements (H to F) and provide appropriate corrections.

RPF-SQX greatly reduces the number of required standards, for a given level of calibration fit, as compared to conventional EDXRF analytical software. As standards are expensive, and can be difficult to obtain for newly developed materials, the utility of having a NEX CG spectrometer can significantly lower costs and reduce workload requirements for routine elemental analysis needs.
