Abstract

The NIST program for environmental Standard Reference Materials (SRMs) includes environmental materials covering a range of different matrices and mass fraction values for analytes of interest. For most SRMs, mass fraction data are accumulated, incidentally, over time, as these SRMs are used routinely in the laboratory for the purpose of quality assurance. Although these analyses are not formal stability studies, the data generated may be useful in assessing material stability. To evaluate the potential for assessing material stability from this type of incidental use of SRMs, results of neutron activation analysis and prompt gamma ray activation analysis performed between 1992 through 2008 were compiled for two biological SRMs that are used routinely, SRM 1547 Peach Leaves and SRM 1566a Oyster Tissue. Data evaluation shows that incidental use of SRMs yields useful information with respect to material stability.
