  • Mass Spectrometer and Method for Direct Measurement of Isotope Ratios
    Publication number: 20120211651
    Abstract: An isotope ratio mass spectrometer is described that obtains direct ratios of atomic isotopes in a monoenergetic beam of negative ions by passing them through a collision cell at specific kinetic energies for which the relative production of positive ions from the negative ions is calculable from the isotopic masses.
