A new approach to isotopic purification has been developed and applied to the production of a small quantity of 244Pu with an isotopic purity >99.996 %, as compared against the standard 244Pu available that displays an isotopic purity of 97.87 %. The presence of Pu isotopes 239Pu, 240Pu, 241Pu and 242Pu have been greatly reduced, allowing for higher spiking levels of the isotopically purified 244Pu tracer. Details of the isotopic purification process will be described along with the effect this improved Pu tracer could have on analytical Pu mass spectrometry measurements.
