Abstract  

The fundamental parameters method (FPM) for X-ray fluorescence (XRF) has been applied to determine the MN, Cr and Sr components of aluminium wires and sheets. The results are compared with neutron activation analysis (NAA) and atomic absorption spectrometry (AAS). The FPM does not require standards, however, it requires the spectra of the pure element for the concentration determination.

Abstract  

For a non-destructive determination of the protein content in soya bean samples, 14-MeV neutron activation analysis /NAA/ was applied. To check the method, results obtained by X-ray fluorescence /XRF/ analysis and the Kjeldahl procedure were compared. For pressed pellet samples of about 1 g and choosing 15 min irradiation and 10 min measuring times the accuracy of the protein determination was found to be 15%.
