[1B04] Preparation of 239Pu, 235U mixed liquid spike for isotope dilution mass spectrometry
Influence of long-term storage of spikes on the determination of Pu and U
Keywords:Accountancy analysis, Isotope dilution mass spectrometry, Spike
A liquid spike containing mg of 239Pu and 235U in a vial was prepared for the determination of Pu and U in nitrate solutions by isotope dilution mass spectrometry using a thermal ionization mass spectrometer. In this study, the influence of long-term storage for 4 years on spike quality was evaluated.
