1.1 This test method covers the determination of 67 elements in uranium dioxide samples and nuclear grade uranium compounds and solutions without matrix separation by inductively coupled plasma mass spectrometry (ICP-MS). The elements are listed in Table 1. These elements can also be determined in uranyl nitrate hexahydrate (UNH), uranium hexafluoride (UF₆), triuranium octoxide (U₃O₈) and uranium trioxide (UO₃) if these compounds are treated and converted to the same uranium concentration solution.
