Abstract
The chemical aspects of isotopic fractionation in a multiple filament thermal ionization source were investigated. Samples of uranium were loaded as nitrates, chlorides and sulphates. The dependence of measured isotopic ratios on the filament material and the chemical form of the loading solution was studied. The dependence of the formation of uranium and its oxide ions on various chemical and instrumental conditions were investigated using tungsten and rhenium filaments.
