Geological and Materials Characterization Applications

A long-standing method for thermometry has been to measure the stable oxygen isotope ratios in carbonate rocks using MS. Uranium/lead isotope ratios, determined by MS, are used to estimate the age of the earth. [Pg.815]

Accurate isotope ratios often require high-precision mass spectrometers. Instruments capable of such high precision are either ICP-TOF-MS or high-resolution magnetic sector ICP-MS instruments of either the single detector or multicollector type. An excellent fundamental [Pg.815]
