Isotopic Abundances

Using a surface-ionization mass spectrometer, the natural U238/U235 abundance ratio in uranium obtained from Great Bear Lake Pitchblende has been measured to be 137.80 ± 0.14. From a survey of results reported in the literature on U234 a best value of 17,325 ± 550 was estimated for the natural U238/U234 abundance ratio. The corresponding isotopic abundances are 0.7204 ± 0.0007 atom % and 0.00573 ± 0.00018 atom % for U235 and U234, respectively.

Sequential Sample

A three-station sequential sample changer has been built for a surface-ionization mass spectrometer used in the analysis of nanogram-sized samples. During the analysis of a sample, the previously analyzed sample is replaced and the next sample to be analyzed is preheated. The delay between completion of one analysis and start of the next is reduced to 1 min or less.
