In a research concerning the study of the separation of uranium isotopes on ion exchanging resins, the problem of very precise isotopic analysis appeared. The existing instrument is a thermal ionisation mass spectrometer built in our institute in 1986. It is equipped with a two filaments ion source and a single ion collector based on a secondary electron multiplier. In 1986, during the homologation procedure, the accuracy was established to be 1% from the measured value. The aim of this work is to overpass this instrumental limitation.
