Abstract: The goal of our work was to modernize the ATLAS M - 86 mass spectrometer in order to perform much accurate and precise isotopic ratio analyses. The improvement was realized by changing the old electronic units and by coupling the mass spectrometer to a personal computer (PC) - with the purpose to allow all of the spectrometer components to be controlled by the computer. Our research was focused on the ionic current measurement. The electronic components realizing this are the following: • the spectrometer interface • the control block of the spectrometer • the ionic currents measurement block | |||||||
