Sequential Mass Spectrometric Analysis of Uranium and Plutonium Employing Resin Bead Technique

摘要

Sequential mass spectrometric analysis of uranium and plutonium employing anion exchange resin bead technique is reported using a high sensitive single stage magnetic analyser instrument, the routinely employed rhenium double filament assembly and 0.5M HNO/sub 3/ as a wetting agent for loading the resin beads. A precision of better than 0.3per cent (2sigma) is obtained on the isotopic ratio measurements. However, extreme care has to be exercised to carry the resin bead experiments under ultra clean conditions so as to avoid pick up of contamination. 8 refs. (Atomindex citation 18:001142)
