Acquisition of a Coulometrics Carbonate Carbon Analyzer and a CE CNS Elemental Analyzer

分析沉积物和岩石中存在的碳、氮和硫对于地球和海洋科学的广泛研究具有重要意义。这笔赠款支持购买Coulometrics无机碳分析仪和CE元素分析仪所需资金的一半，这些分析仪将安装在南加州大学洛杉矶分校地球科学系并进行操作。南加州大学承诺提供购买所需的剩余资金。具体地说，Coulometrics CM 140将用于分析最近沉积物和岩石中的碳酸盐百分比，CE 2500将用于分析总碳、氢、氮和硫。该仪器将取代自60年代初S以来一直在该部门使用的LECO分析系统，提供更高的灵敏度、分析速度和准确性。它还将提供增强的能力，因为它允许测量氮和氢。该设备将促进沉积地质学、地球化学、古海洋学和古生物学领域的10名教职员工的研究计划。它还将用于教学，特别是在碳酸盐地层学、地球化学和古海洋学的研究生班。南加州大学以外的用户还将能够为适当的研究项目协商机器时间。*

9817651MuttiAnalysis of the carbon, nitrogen and sulfur present in sediments and rocks is of fundamental importance for research in a broad spectrum of the Earth and Ocean Sciences. This grant supports one-half of the funds needed for the acquisition of a Coulometrics Inorganic Carbon Analyzer and CE Elemental Analyzer that will be installed and operated in the Earth Sciences Department at the University of Southern California, Los Angeles. USC is committed to providing the remaining funds required for the purchase. Specifically, the Coulometrics CM 140 will be used for analyzing carbonate percentage in recent sediments and rocks and the CE 2500 will be used for analysis of total carbon, hydrogen, nitrogen and sulfur. This instrumentation will replace the LECO analysis system that has been used in the department since the early 60's, providing increased sensitivity, speed of analysis and accuracy. It will also provide enhanced capability as it permits measurements of nitrogen and hydrogen. This equipment will facilitate the research programs of ten faculty members spanning the fields of sedimentary geology, geochemistry, paleoceanography and paleontology. It will also be of instructional use, particularly in graduate classes in carbonate stratigraphy, geochemistry and paleoceanography. Users outside of USC will also be able to negotiate for machine time for appropriate research projects.***
