Summary

Modern analysis of trace elements has been carried out for many years. The quality of analysis results however still leaves a lot to be desired. Problems arise from contaminations caused by ubiquitous distribution of the trace elements during preparation of the samples. It is shown where in the laboratory sources of contamination are to be found and how they can be avoided. Experience with sample preparation, a decomposition system with low contamination and cleaning methods are described.
