MRI-R2: Acquisition of an isotope ratio mass spectrometer

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。马萨诸塞州波士顿大学（UMass Boston）从重大研究仪器计划获得资金，以支持购买同位素比质谱仪（IR-MS），以支持生态学、地球化学和地球化学研究。 该仪器被整合到马萨诸塞大学波士顿环境分析实验室（EAL）中，可以进行广泛的跨学科研究，例如（1）水、溶解有机碳和碳酸盐物质的同位素分析，（2）溶解有机碳和有色溶解有机物（CDOM）中δ 13-C的测量，（3）单个化合物的同位素分析（如脂肪酸和多环芳烃）;（4）组织、全岩和岩石有机显微组分的同位素测量。 新设备支持的研究结果将发表在同行评审期刊上，并通过学生和教师在地区和国家会议上的演讲进行传播。 麻省大学波士顿分校是大波士顿地区唯一的公立大学，也是新英格兰最多元化的公立4年制大学。该仪器通过纳入整个科学和数学学院本科生和研究生一级的环境课程，大大加强了对代表性不足的少数民族学生的研究和培训。 此外，我们的学生通过独立的研究项目和在科学会议上展示他们的发现，获得了额外的经验和专业知识的深度。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The University of Massachusetts Boston (UMass Boston) received funds from the Major Research Instrumentation Program to support acquisition of an Isotope Ratio Mass Spectrometer (IR-MS) to support ecological, biogeochemical, and geochemical research. The instrument is incorporated into the UMass Boston Environmental Analysis Laboratory (EAL) enabling broad transdisciplinary research such as (1) isotopic analysis of water, dissolved organic carbon, and carbonate materials, (2) measurement of delta 13-C in dissolved organic carbon and colored dissolved organic matter (CDOM), (3) isotopic analysis of individual compounds (e.g. fatty acids and polyaromatic hydrocarbons), and (4) isotopic measurements in tissues, whole rocks and organic macerals from rocks. Results from the research enabled by the new equipment will be published in peer-reviewed journals and disseminated through student and faculty presentations at regional and national meetings. UMass Boston is the only public university in the greater Boston area and is the most diverse public 4-year institution in New England. The instrumentation significantly enhances research and training of underrepresented minority students through integration into environmental courses throughout the College of Sciences and Mathematics at the undergraduate and graduate levels. In addition a significant number of our students gain additional depth in experience and expertise through independent research projects, and presentation of their findings at scientific meetings.
