The National Institute of Standards and Technology is in the process of certification for a new supply of the botanical standard reference material (SRM) 1573, tomato leaves. This renewal SRM 1573a has already been analyzed by instrumental neutron activation analysis (INAA) for 18 elements with 12 replicates and sample sizes averaging {approximately}140 mg. Elements determined by INAA were selected according to the needs of the SRM program and include some with short half-lives (aluminum, vanadium, calcium, magnesium), some with intermediate half-lives (sodium, potassium, manganese, barium, lanthanum, rubidium), and some with long half-lives (iron, chromium, zinc, cobalt, selenium, thorium, scandium, and antimony). The data obtained will also be used for homogeneity evaluation. During the initial evaluation and certification analyses, a number of potential errors and interferences were identified.
