Rigaku publishes new WDXRF Application: Determination of Metals in Copper Concentrate by Advanced Correction Method for Fused Beads
Date:2/12/2013

on, such as the analysis of alloys.

The fusion method is an effective sample preparation technique for accurate analysis of a wide variety of powder samples, including minerals and ores, by XRF spectrometry. Samples are prepared as fused beads, thus eliminating heterogeneity due to grain size effects and mineralogical composition. During the calibration, all of the elements were treated as oxides. Correction coefficients applied to the matrix correction in the calibration were theoretically calculated by the built-in Fundamental Parameter (FP) software. In order to take advantage of the fusion method, however, appropriate corrections for errors resulting from fusion processes are required. Possible errors in the fusion process are: weighing inaccuracies, loss on ignition (LOI), gain on ignition (GOI), decomposition of oxidizing agents and evaporation of flux. The results demonstrate that the fusion method can be successfully employed for the analysis of copper concentrate.
