Development of Isotope and Chemical Ratio Measurements by FTMS

该奖项提供了两年的支持， 旨在适应傅立叶技术的发展工作 变换质谱法（FTMS）用于同位素分析 天然地质样品FTMS可能是一种快速， 相对便宜的同位素微量分析方法，但 分析地质上感兴趣的元素（例如， 用铀铅放射性衰变测定岩石年龄 系统学）提出了关于不需要的同位素的问题 分馏效应，必须解决前FTMS可以 在地球化学研究中得到了很好的应用。

This award provides two years of support to continue developmental work aimed at adapting the technique of Fourier Transform Mass Spectrometry (FTMS) for the isotopic analysis of natural geological samples. FTMS is potentially a fast and relatively inexpensive method of isotopic microanalysis, but the analysis of geologically interesting elements (for example, dating the age of rocks using uranium-lead radioactive decay systematics) raises problems regarding unwanted isotopic fractionation effects that must be resolved before FTMS can be used profitably in geochemical research.
