Recent developments in isotope-ratio mass spectrometry for geochemistry and cosmochemistry
, 2016 Mass spectrometry is fundamental to measurements of isotope ratios for applications in isotope geochemistry, geochronology, and cosmochemistry. Magnetic-sector mass spectrometers are most common because these provide the best precision in isotope ratio ...
