Acquisition of Gas Chromatograph-Isotope Ratio Mass Spectrometer

该奖项提供了总额的约22%， 需要获取气相色谱同位素比质量 光谱仪此次收购所需的额外资金 是由能源部和俄克拉荷马州大学共同发起的这 仪器将被用来确定同位素组成的 沉积物中复杂有机混合物中的单个组分 来自不同地质源物质的碎屑。个人 现代沉积物、石油、源岩提取物中的成分，或 热解产物可以通过GC分离，燃烧成碳， 二氧化物和它们的同位素组成在真实的时间确定。 同位素数据目前在文献中的有机物， 不同年龄的沉积物通常是所有沉积物的平均值。 混合物中的有机成分;这是不可能的， 要确定这种同位素是非常困难和昂贵的 使用传统技术合成单个组分。 将使用单个组分的同位素组成 作为生物标志物，可能在重建 含有这些物质的沉积物的古历史。

This award provides for approximately 22% of the total amount needed to acquire a gas chromatograph-isotope ratio mass spectrometer. The additional funding necessary for this acquisition has been committed by DOE and the University of Oklahoma. This instrument will be used to determine the isotopic composition of individual components in complex organic mixtures in sedimentary detritus derived from diverse geologic source materials. Individual components in Recent sediments, oil, source rock extracts, or pyrolysis products can be separated via GC, combusted to carbon dioxide, and their isotopic composition determined in real time. Isotopic data currently in the literature for organic matter in sediments of varying age are typically average values of all organic components in the mixture;it has been impossible or exceedingly difficult and expensive to determine the isotopic composition of individual components using traditional techniques. The isotopic composition of the individual components will be used as biomarkers and may be valuable in reconstructing the paleohistory of sediments containing these materials.
