In close collaboration with the Belgian Nuclear Research Centre (SCK-CEN), JRC scientists assessed the reliability of different calibration standards for neutron activation analysis. The study compared a newly released certified reference material (CRM) with five other (existing ones) to demonstrate that all give equivalent results.
Neutron activation analysis with k0 standardisation (k0-NAA) is a very powerful measurement technique that can determine many elements simultaneously without time-consuming sample preparation. It does, however, require a CRM for reliable calibration. The reliability of the CRM is therefore crucial for the overall reliability of measurement results. The JRC has produced a number of such reliable CRMs, dating back to 1991.
