Abstract

Optimisation of the analysis of a non-conducting material in a copper matrix by glow discharge atomic absorption spectroscopy was undertaken. The optimum copper content and glow discharge sputter conditions were determined using experimental design. The chosen design detected a threshold value for burn conditions above which conditions should be maintained. Using post- threshold burn conditions, the iron content of two certified reference materials (CRMs) was determined (BCS-CRM 395 bauxite and NIST-CRM 1645 river sediment).
