Abstract  

The contribution of different analytical techniques to the results of a recent IAEA intercomparison (A-11) of the determination of the inorganic constituents of a milk powder sample is discussed. In all, 43 laboratories from 24 countries reported results on 40 elements, “recommended” concentrations for 14 elements were established. NAA was the most important of the 9 techniques used in this run, it contributed 40% of all the results and all the results for 7 elements. Accuracy and precision of NAA proved to be good compared to those of other methods.
