Multi-Element Preconcentration from Technical Alloys

Abstract

In recent years the multi-element analysis of technical alloys has become an important field of interest in routine analysis. This is valid not only for some of the new developed materials with very special qualities, but also for many well proved alloys with a wide spread application. As main reason for this development in analysis one may consider the increasing demand in the purity of materials as a consequence of the often found correlation between mechanical, electrical etc. properties of metals and their content of trace elements. Additionally the increasing use of recycled metals leads to an increase of the number of elements present in considerable amounts in the alloying materials. So, even the search for elements generally considered exotic suddenly may become an important task in routine analytical work.
