Abstract  

Investigations were carried out on the determination of isotopic composition of boron using Cs2BO 2 + ion and thermal ionisation mass spectrometry. The results show distinct advantage over the normally used Na2BO 2 + ion.

Abstract  

K-factors (= certified isotope ratio/observed isotope ratio) are determined for the isotope abundance measurements of uranium and plutonium by thermal ionisation mass spectrometry. An mdf of 0.07% and 0.18% per mass unit differing by a factor of about 3, is obtained for uranium and plutonium, respectively, employing double rhenium filament assembly in the ion source and Faraday cup as the detector using the presently available isotopic reference materials of uranium and plutonium.
