    Significance and Use

    5.1 This test method may be run together with Test Method C1432 to analyze for trace impurities in Pu metal. Using the technique described in this test method and the technique described in Test Method C1432 will provide the analyst with a more thorough verification of the impurity concentrations contained in the Pu metal sample. In addition, Test Method C1432 can be used to determine impurity concentrations for analytes such as Ca, Fe, Na, and Si, which have not been determined using this test method.

    5.2 This test method can be used on Pu matrices in nitrate solutions.

    5.3 This test method has been validated for use on materials that meet the specifications described in Specification C757 and Test Methods C758 and C759.

    5.4 This test method has been validated for all elements listed in Table 1.

    (A) Without outlying value.

    1. Scope

    1.1 This test method covers the determination of trace elements in plutonium (Pu) materials such as Pu metal, Pu oxides, and Pu/uranium (U) mixed oxides. The Pu sample is dissolved in acid, and the concentration of the trace impurities are determined by Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS).

    1.2 This test method is specific for the determination of trace impurities where the samples are dissolved and the oxidation state is adjusted to the Pu(IV) and, if applicable, the U(VI) state. It may be applied to other matrices; however, it is the responsibility of the user to evaluate the performance of other matrices.

    1.3 The use of a quadrupole ICP-MS or a high resolution ICP-MS (HR-ICP-MS) can be employed in all applications relevant to this test method. HR-ICP-MS is a better option in many cases since it can reduce or potentially eliminate interferences encountered in the following complex sample matrices.

    1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
