Purchase of New Gas Source, Isotope Ratio Mass Spectrometer

该奖项提供了购买气源同位素比质谱仪所需资金的一半，该质谱仪将由华盛顿卡内基研究所地球物理实验室安装和操作。卡内基研究所承诺提供所需的剩余资金。近年来气源、同位素比质谱仪设计的改进，极大地扩展了稳定同位素地球化学在生命演化和无机地球化学过程研究中的应用。这台仪器将用于若干研究项目，包括研究地壳和上地幔的传质过程和生物化学代谢反应中的同位素分馏。

This award provides one-half the funds required for the acquisition of a gas-source isotope ratio mass spectrometer to be installed and operated by the Geophysical Laboratory of the Carnegie Institution of Washington. The Carnegie Institution is committed to providing the remaining funds needed. Recent improvements in the design of gas-source, isotope ratio mass spectrometers have greatly expanded the application of stable isotope geochemistry to research in the evolution of life and inorganic geochemical processes. This instrument will be used in a number of research projects including studies of mass transfer processes in the Earth's crust and upper mantle and isotopic fractionation in biochemical metabolic reactions.
