Acquisition of a New Continuous-Flow Stable Isotope Mass Spectrometer and Two Elemental Analyzers for Support of the University of Southern California Stable Isotope Facility

该合同将为南加州大学稳定同位素设施提供资金，用于购买一台新的稳定同位素比质谱仪（IRMS）和两套外围系统--一台用于15 N/14 N和13 C/12 C同位素连续流应用的元素分析仪和一台用于有机物D/H和18 O/16 O分析的高温热解系统（TCEA）。新仪器将增强实验室的分析能力，提高整体分析效率，并最大限度地减少停机时间。 11名普通教师和他们的学生使用南加州大学的设施，因为它是一个开放使用的实验室，它也是一个教育设施。学生接受操作和维护仪器的培训，并指导如何准备质谱样品。该实验室每年雇用几名本科工读学生，其中一些学生由于在实验室的经验而从事环境研究。

This award will provide funds to acquire a new stable isotope ratio mass spectrometer (IRMS), and two peripheral systems - an elemental analyzers for continuous flow applications of 15N/14N and 13C/12C isotopes and a high temperature pyrolysis system (TCEA) for analysis of D/H and 18O/16O analyses of organics - for the University of Southern California stable isotope facility. The new instrumentation will augment the labs analytical capabilities and improve overall analytical efficiency and minimize downtime. Eleven regular faculty and their students use the USC facility and, because it is an open-use laboratory, it is also serves to an educational facility. Students are trained to operate and maintain the instruments as well as being instructed in how to prepare samples for mass spectrometry. The laboratory employs several undergraduate work study students each year, and a number of these students have gone on to careers in environmental studies as a result of their experiences in the laboratory.
