In industrial laboratories, a great diversity of samples is usually presented for analysis (alloys, powders, solutions, …). Fast results are invariably required so that methods with minimal preparation times have to be developed. This paper discusses a method for quantitative analysis of metallic samples in the form of clippings or odd-shaped fragments where the specimen surface does not cover the total surface of the sample holder. In some laboratories it is common practice to use sample holders with a small orifice to analyse sample fragments, but this method strongly reduces the fluorescent intensities. We have the feeling that a method that uses the whole surface of the specimen should be much welcomed.

Calculation methods for quantitative analysis, energy dispersion, and inhomogeneous samples are current areas in x-ray analysis which offer hope of reducing analysis costs. Other areas which extend the capabilities of x-ray analysis include improved analyzer crystals, diffraction gratings, and effects of valence on spectral lines. Electron spectrometry promises to be a valuable technique for low atomic number elements.

K X-ray spectra have been obtained from Platinum-Group Element (PGE) minerals using 40 MeV Proton-Induced X-ray Emission. It is possible to resolve all four component X-ray lines for the PGEs. In cases where there is more than one PGE present, some K X-ray lines may overlap, but in all cases, there were single lines available for quantitative analysis. The spectrum obtained from the sperrylite during exposure to the proton beam beam contained Au X-rays. The presence of the Au can be attributed to (p,xn) reactions with Pt, induced by proton bombardment of the sample. The intensity of Au X-ray lines in the spectrum is proportional to the amount of Pt in the sample and the cross-section for (p,xn) reactions between Pt and Au at 40 MeV.
