Standard Test Method for Determination of Impurities in Uranium Dioxide by Inductively Coupled Plasma Mass Spectrometry
|Publication Date:||10 September 1995|
1.1 This test method covers the determination of 61 elements in uranium dioxide samples by inductively coupled plasma mass spectrometry (ICP-MS). The elements are listed in Table 1 along with their lower reporting limits.
1.2 Similar levels of these elements in other uranic compounds can also be determined if they are treated and converted to the same uranium concentration solution.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use. For a specific warning statement, see Note 1.
Note 1-The ICP-MS is a source of intense ultra-violet radiation from the radio frequency induced plasma. Protection from radio frequency radiation and UV radiation is provided by the instrument under normal operation.
1.4 The test method for the additional elements boron, sodium, silicon, phosphorus, potassium, and calcium is given in Appendix X1.
1.5 The test method for technetium-99 is given in Appendix X2.
