Application of thermal ionisation mass spectrometry for the determination of isotopic abundance and concentration of elements

Thermal ionisation mass spectrometry (TIMS) is an effective tool for measuring the precise and accurate isotopic abundances of solid samples. In favourable cases, elemental concentration could be determined by employing isotopic dilution method. The mass spectrometry is being analysed at Chemistry Division, Chemical Group, Indira Gandhi Centre for Atomic Research, both for the determination of isotopic ratios and elemental concentrations for samples related to post irradiation examination of fast and thermal reactor fuel solutions. A brief over view of these activities in given
