Resin Bead Mass Speclromelry An Analytical Technique for Safeguarding Pu and U

Single anion resin beads have been used to extract Pu and U from spent fuel dissolver solutions and to serve as sample-loading devices for isotopic mass spectrometric analysis. Because of the small quantities involved (1-3 ng), shipping and handling of the samples are much simplified in comparison to more conventional techniques. The technique is described in some detail and results of a series of evaluative experiments are given. The technique gives results comparable to those obtained by conventional mass spectrometry.
