Plutonium isotopic analyses via a single carbonized rhenium filament has been used for many years. One of the main limitations on the method is the difficulty of maintaining reproducible control of isotopic fractionation. It was previously shown that an electroplated platinum overlay is very effective in controlling the fractionation from rhenium filaments. The overplate of platinum on carbonized rhenium also reduces fractionation and produces a much longer lived stable ion beam over the life time of the sample run. A rapid platinum overplate technique was developed for the carbonized rhenium filament by using thermal decomposition of chloroplatinic acid.
