A mass spectrometer panticularly suitable for measuring small variations of the isotopic-abundance ratio in light gaseous elements was entirely designed and put into operation at the Physics Department of the University of Genoa. Three instruments, differing from each other in minor details, were built, two of which are in use at the Physics Department in Genoa. The third instrument was handed over to the Laboratory of Nuclear Geology at University of Pisa, where it is routinely measuring natural isotopic abundances, including paleotemperatures. Details are given of special features of the mass spectrometer which make it different from similar models constructed abroad. The operating conditions of the instrument are given. The over-all sensitivity of the mass spectrometer is about one part over two million. A precision of one per mil in the measurement of isotopic abundance variations can be easily reached in the case oi favorable isotopic ratios. (auth)
