X-Ray Fluorescence Spectrometry (XRF)

Equipment & location: B352/B354

For routine X-ray fluorescence analysis, powdered sample material is fused to a glass disc. Therefore, the powered samples (grain sizes <62 μm), as well as two Fluxana-samples are dried at ~100 °C, weighed, and melted on different heaters at temperatures between 400-1150 °C. The melt is then quenched to a glass disc and analyzed. We analyze major elements (wt% oxide) and some trace elements (ppm).

Equipment: PANalytical AXIOS Advanced

Some machines are used in combination with the XRF and the XRD

  • Eltra CS 2000: determination of sulfur (S) und carbon (C)
  • Euro EA Elemental Analyzer: determination of H2O/CO2
  • Thermo Scientific Diomex ICS-1100: determination of anions (fluoride, chloride)
  • Pyro-hydrolysis: separation of fluor (F) und chlor (Cl)
  • Fe(II)-Analysis
