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).
