Description
Summary:Seven steel samples considered as reference materials have been analysed by atomic emission spectrometry with inductively coupled plasma (ICP-AES), atomic absorption spectrometry with flame and graphite furnace atomization (FAAS, GFAAS), differential pulse anodic stripping voltammetry (DPASV), X-ray fluorescence analysis with total reflection sample carrier (TXRF), and instrumental neutron activation analysis (INAA). Totally, 18 elements were determined. Over 90% of all results were in good agreement with the values determined by wet analytical methods. The deviations can be explained by systematical errors for special elements in distinct methods and by statistical errors, mainly at very low concentrations because some elements, in the low ng/g region, are not homogeneously distributed in the given material.
