Lithogenic isotopes of strontium (Sr), neodymium (Nd), and lead (Pb) are a powerful tool for the study of the composition and origin of pre-historic ceramics and their raw materials. Despite their use in classical geochronology and isotope-geochemical provenance studies of rocks and minerals, Sr, Nd, and Pb isotope ratios have so far scarcely been used

A Mass Spectrometer for Isotope and Gas Analysis
Review of Scientific Instruments, 1947A mass spectrometer suitable for routine isotope analyses of the lighter elements is described. Complete electronic circuits are given. An all metal mass spectrometer tube is employed. A null method of determining relative abundances of the elements carbon, nitrogen, and oxygen is used.
