## Standard Practice for the Ion Exchange Separation of Uranium and Plutonium Prior to Isotopic Analysis

historical
 Organization: ASTM International Publication Date: 10 January 2001 Status: historical Page Count: 4 ICS Code (Fissile materials and nuclear fuel technology): 27.120.30
##### scope:

1.1 This practice is for the ion exchange separation of uranium and plutonium from each other and from other impurities for subsequent isotopic analysis by thermal ionization mass spectrometry. Plutonium-238 and uranium-238, and plutonium-241 and americium-241, will appear as the same mass peak and must be chemically separated prior to analysis. Only high purity solutions can be analyzed reliably using thermal ionization mass spectrometry.

1.2 This standard may involve hazardous material, operations, and equipment. 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.
