This study compares the analytical performance of several existing materials as k0-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 k0-NAA using IRMM-530, IRMM-530R, ERM-EB530, IRMM-533, IRMM-528R and IRMM-534 as comparator material. The different k0-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 k0-NAA and that switching from IRMM-530 or IRMM-530R to ERM-EB530 should not lead to changes in k0-NAA results.
