Abstract

Instrumental neutron activation analysis (INAA) as carried out at the National Institute of Standards and Technology (NIST) is inadequate for de-termining Al, Ni, and V at the levels found in the newly prepared Standard Reference Material (SRM) 1577c Bovine Liver. High matrix activity limits the INAA sensitivity for Al and V, and the low fast-neutron flux at the NIST Center for Neutron Research prevents the determination of Ni via 58Co. To overcome shortcomings in the value assignment, the authors initiated a cooperative approach using NAA with previously established chemical separation procedures and with significantly different neutron sources to determine Al and V with pre-irradiation separation of the elements at NIST, and V and Ni with post-irradiation separation at the Nuclear Physics Institute (NPI) Ře . The determinations were confirmed with the analyses of several SRMs, the results for V from the two laboratories were found in agreement. The work supported the certification of mass fraction values for V and Ni in SRM 1577c.
