Neutron Activation Analysis with Pe- and Post-Irradiation Chemical Separation for the Value Assignments of AL, V, and Ni in the New Bovine Liver SRM 1577C

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.
