The Isotopic Ratios Measurement of Plutonium by TIMS

    Graphical Abstract
    • Abstract
  • The plutonium isotopic abundance ratio was analyzed by thermal ionization mass spectrometry (TIMS) with the ion counting technique. The ion counting system was developed and applied by our lab teem on the MAT261. It is verified with the certificated isotopic reference material. Using 3×10－9 g of plutonium, the combined standard uncertainty of ratio of 240Pu to 239Pu plutonium isotopes in 3 ng is 0.070%.
