This award provides funds for the acquisition of a gas chromatograph and combustion line to be interfaced with a stable isotope ratio mass spectrometer in the Department of Environmental Sciences at the University of Virginia. The new instrumental system will enable the determination of nitrogen and carbon isotopic compositions of the individual molecular components of mixtures of complex organic compounds. Such analytical capabilities offers enhanced interpretation of the source and history of organic material preserved in the natural fossil record and will be used in geological, biological, and anthropological research.

该奖项为获得气相色谱和燃烧线的获取提供了资金，该奖项与弗吉尼亚大学环境科学系的稳定同位素比率质谱仪相连。 新的仪器系统将能够确定复杂有机化合物混合物的各个分子成分的氮和同位素组成。 这种分析能力提供了对保存在自然化石记录中的有机材料的来源和历史的增强的解释，并将用于地质，生物学和人类学研究。
