0842268KaufmanThis grant supports acquisition of equipment to upgrade the stable isotope facility at the University of Maryland, Department of Geology. Specific equipment that will be acquired includes: 1) a Carbon/Sulfur analyzer (CS analyzer) for combustion of bulk samples for total S, total C, and total inorganic C (TIC) abundances of bulk samples; and 2) a gas chromatograph/combustion/pyrolysis (GC/C/P) inlet system for the separation of organic extracts from sediments and sequential combustion for C and H isotope compositions. The equipment will support PI and colleague studies of biogeochemical processes and climate variability on the early Earth (Archean and Proterozoic eons) and allow expansion of this research through new analytical capability for characterization of compound specific stable isotopic ratios and the structure of organic molecular compounds preserved in ancient sedimentary rocks. The expanded capabilities fo this laboratory will also support visiting scientists, graduate, undergraduate and high school student projects.

0842268考夫曼这笔赠款用于支持购置设备，以升级马里兰州大学地质系的稳定同位素设施。 将购置的具体设备包括：1）一台碳/硫分析仪（CS分析仪），用于燃烧散装样品，测定散装样品的总硫、总碳和总无机碳（TIC）丰度; 2）一台气相色谱/燃烧/热解（GC/C/P）入口系统，用于从沉积物中分离有机提取物，并连续燃烧，测定碳和氢同位素组成。 该设备将支持PI及其同事对早期地球（太古代和元古代）的地球化学过程和气候变化的研究，并通过新的分析能力扩展这项研究，以表征化合物特定的稳定同位素比率和保存在古代沉积岩中的有机分子化合物的结构。 该实验室的扩展能力还将支持访问科学家，研究生，本科生和高中学生项目。
