0931205FilleyThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Granted funds will support acquisition of a new gas chromatograph/mass spectrometer (GC-MS) and upgrade of an existing stable isotope mass spectrometer within the biogeochemistry laboratory of PI Tim Filley, Department of Earth & Atmospheric Sciences Purdue University. The new quadrupole GC-MS will replace an early 1990?s era GC/MS system which is experiencing increasing downtime and is no longer supported by the manufacturer. Upgrade of an existing PDZ-Europa 20/20 stable isotope ratio mass spectrometer (SIRMS) will include replacement of antiquated communication and power supply electronics, operating software and a high temperature pyrolysis system to permit analysis of the Hydrogen isotopic composition of lipids. These instrument upgrades will support PI research on the biogeochemistry of soil organic matter and riverine borne dissolved organic matter (DOM), support an active outreach program to Native American students in Tribal Colleges within the Red Lake Nation and through collaboration with faculty at Bemidji State University, MN. PI research has relevance to understanding the role of soils in climate change and may influence future sustainable agricultural practices. ***

0931205Filley 该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。 赠款将支持普渡大学地球与大气科学系 PI Tim Filley 生物地球化学实验室内购买一台新的气相色谱仪/质谱仪 (GC-MS) 以及升级现有的稳定同位素质谱仪。 新型四极杆 GC-MS 将取代 1990 年代早期的 GC/MS 系统，该系统的停机时间越来越长，并且制造商不再提供支持。 现有 PDZ-Europa 20/20 稳定同位素比质谱仪 (SIRMS) 的升级将包括更换过时的通信和电源电子设备、操作软件和高温热解系统，以分析脂质的氢同位素组成。这些仪器升级将支持 PI 对土壤有机质和河流溶解有机质 (DOM) 的生物地球化学研究，并通过与伯米吉州立大学的教师合作，支持红湖国家部落学院的美国原住民学生的积极外展计划，明尼苏达。 PI 研究有助于了解土壤在气候变化中的作用，并可能影响未来的可持续农业实践。 ***
