A rapid automated flow injection analysis (FIA) procedure was developed for efficient separation of Am and Pu from each other
and from interfering matrix and radionuclide components using a TRU-resin™column. Selective Pu elution is enabled via on-column reduction. The separation was developed using on-line radioactivity
detection. After the separation had been developed, fraction collection was used to obtain the separated fractions. In this
manner, a FIA instrument functions as an automated separation workstation capable of unattended operation.
