Abstract
This chapter introduces the reader to mass spectrometry and the instruments used to determine high-precision isotope ratios. These instruments separate ion beams, of charged atomic particles with kinetic energies of several keV, by mass-to-charge ratio. Quantitative detection of these energetic charged particles is a key technology in mass spectrometry. For isotope ratio determination the main detector types are Faraday cups, the Daly detector, and discrete dynode secondary electron multiplier (SEM) ion counters. For high-precision applications, arrays of these detectors are arranged to collect several ion beams simultaneously. Examples are given for the application of these detectors in geology, environmental sciences, and nuclear safeguards.
