Acquisition of a Gas Chromatograph-Quadrupole Mass Spectrometer and upgrade to an existing Stable Isotope Mass Spectrometer for Continued Biogeochemical Research.

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)资助的。获得的资金将用于购买一台新的气相色谱仪/质谱仪(GC-MS)，并升级普渡大学地球与大气科学系皮蒂姆·菲利生物地球化学实验室现有的稳定同位素质谱仪。新的四极GC-MS将取代1990年代初S时代的GC/MS系统，该系统正在经历越来越长的停机时间，不再受到制造商的支持。升级现有的PDZ-Europa 20/20稳定同位素比质谱仪(SIRMS)将包括更换陈旧的通信和电源电子设备、操作软件和高温热解系统，以便能够分析脂类的氢同位素组成。这些仪器升级将支持PI对土壤有机质和河流中溶解有机质(DOM)的生物地球化学研究，支持红湖民族部落学院美洲原住民学生的积极外联计划，并通过与明尼苏达州贝米吉州立大学的教师合作。PI研究与了解土壤在气候变化中的作用有关，并可能影响未来的可持续农业实践。***

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. ***
