The quantification of technetium in generator-derived pertechnetate using ICP-MS.

摘要: Abstract Previous analytical methods employed to measure 99 Tc : m ratios in chromatographic generators, derived from fission-based Mo , were limited monitoring the low activity over extent of their elution regimes. For regulatory purposes, ICP-MS was total technetium generator eluates down a level 200 pg ml−1 (200 ppt). Measured compared very well with theoretically computed values, ranging 47:1 for first long ingrowth time 1.4:1 17th short time.
