Comparison of k (0) NAA analysis results of four different reference materials using six various materials for comparator factor calculation

摘要

This study compares the analytical performance of several existing materials as k (0)-NAA comparator materials (Al-0.1 % Au, Al-0.1 % Ag, Al-1.0 % Co and Al-2.0 % Sc) with the new Al-0.1 % Au material (ERM-EB530). Trace elements in four reference materials (bakelite, fly ash, biological tissue and sediments) were analysed by k (0)-NAA using IRMM-530, IRMM-530R, ERM-EB530, IRMM-533, IRMM-528R and IRMM-534 as comparator material. The different k (0)-NAA comparators gave reliable, precise and accurate results for all elements and matrices. The study demonstrated that the new Al-0.1 % Au comparator (ERM-EB530) is fit for k (0)-NAA and that switching from IRMM-530 or IRMM-530R to ERM-EB530 should not lead to changes in k (0)-NAA results.
