Sample contamination as a source of error in trace-element analysis of biological samples

J Versieck et al. Talanta. 1982 Nov.

Abstract

Trace-element levels estimated by different investigators are often disparate. It is becoming increasingly evident that sample contamination may explain some of the discrepancies. A method has been developed for the direct estimation of potential errors. This shows that extraneous additions occurring during sample collection and preparation may give rise to grossly misleading results on subsequent analysis.
