Analysis of coal by FP method

The analysis of coal is demonstrated, with specific emphasis on the measurement of Na2O, using the Fundamental Parameters (FP) approach with Matching Library.


During the mining, processing and burning of coal, process monitoring and control are vital to the efficiency and quality of the final product. Whether screening incoming raw materials, monitoring production processes, or QA/QC out-processing, a fast, simple, and accurate method for analyzing samples is important throughout the production cycle. Specific attention is often given to the sodium content (Na2O). High sodium content can combine with sulfur or aluminum and silicon to form sodium sulfate or sodium alumina-silicate compounds. Such compounds, formed when burning high sodium coals, can lead to fouling of the cyclone or heat exchange surfaces. Rigaku offers the NEX CG EDXRF analyzer to meet the challenge of analyzing low sodium coals. Rigaku NEX CG utilizes secondary excitation and polarization to provide unmatched sensitivity, with best-in-class detection limits for the light elements like Na. The NEX CG can reliably measure from Na to U and is simple enough for use by non-technical operators, yet powerful enough for expert use in research and development.

Rigaku 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. Read more...
