Abstract

The first results are presented of an analysis of light platinoids (Ru, Rh, Pd) in silicate rocks, ores and references by the SRXFA technique. To improve the reproducibility of the analysis results, the sample has been scanned with a SR beam and the data obtained averaged over a large area. The influence of combinatorial lines in the SRXFA spectra, caused by the pulse nature of the radiation, has been observed. The detection limits for Ru, Rh and Pd were 0.017–0.07 ppm at a 10 3 s in the absence of conflicting spectral lines.
