Trace element analysis of steels with ICP-MS.
In a review with 12 refs. the accuracy of routine application of ICP-MS in steel industry is discussed. The main problems are the overlap of the spectra from polyat. ions and matrix effects. The limits of detn. are in the very low mg/g or, for some elements, in the submicrogram region when analyzing dissolved steel samples at compromise operational conditions for multielement anal.
