  • Method for measuring ionic currents, and a catching device therefor
    Patent number: 6472659
    Abstract: The invention relates to a novel method for measuring ionic currents when determining isotope ratios and suing a mass spectrometer. Two or more ionic currents are measured in parallel, that is to say caught by catchers and evaluated via respectively assigned electronic measuring system. The assignments between catchers and electronic measuring systems are changed as time progresses.
