Acquisition Isotope Ratio Mass Spectrometers

项目摘要

A grant has been awarded to the University of Miami under the direction of Dr. Leonel Sternberg for the acquisition of two stable isotope ratio mass spectrometers. These two instruments will provide isotopic analysis of samples from several funded research projects at the University of Miami and other institutions. The two instruments will also serve as teaching tools for graduate students involved in the above projects, as well as introducing undergraduate students to state of the art scientific techniques. The acquisition of these automated instruments will greatly facilitate the generation of data by different research groups at UM. First, by being an in-house facility, it will greatly increase the speed by which results are obtained. Second, the instruments will be tailored to the specific analysis necessary by each group. Lastly, being automated systems, these instruments will greatly decrease the cost of sample analysis. The research projects that will be advanced by the utilization of this instrument include research in topics such as: water conservation in the Everglades and savanna ecosystems of central Brazil, development of analytical tools towards the understanding of past and present climate change and aspects of nitrogen metabolism. These two instruments will also serve an important part in the University of Miami commitment towards graduate and undergraduate education. Graduate students will have full access to the instrumentation once trained in their operation. Graduate students will realize the full potential of this "high tech" approach towards solving problems ranging in scale from metabolic biology to global ecology. This will be one of the many efforts at the University of Miami to prepare our graduate students towards understanding the application of state of the art scientific techniques to biological problems. In addition one of the CoPI's has several outreach programs focused in bringing under represented minorities to the research experience and these instruments will be utilized towards this goal. The impact of the research utilizing these two instruments will cover several important areas such as water management in South Florida, biomedical aspects of metabolism, climate change and hydrology.

在莱昂内尔斯滕贝格博士的指导下，迈阿密大学获得了一笔赠款，用于购买两台稳定同位素比质谱仪。这两台仪器将对来自迈阿密大学和其他机构的几个资助研究项目的样品进行同位素分析。这两种仪器还将作为参与上述项目的研究生的教学工具，并向本科生介绍最先进的科学技术。这些自动化仪器的购置将极大地方便UM不同研究小组的数据生成。首先，作为一个内部设施，它将大大提高获得结果的速度。第二，这些工具将根据每个小组所需的具体分析加以调整。最后，作为自动化系统，这些仪器将大大降低样品分析的成本。将通过利用这一工具推进的研究项目包括以下专题的研究：巴西中部大沼泽地和稀树草原生态系统的水资源保护，为了解过去和现在的气候变化和氮代谢方面开发分析工具。这两项文书也将成为迈阿密大学致力于研究生和本科教育的重要组成部分。研究生一旦接受操作培训，将完全可以使用仪器。研究生将认识到这种“高科技”方法的全部潜力，以解决从代谢生物学到全球生态学的各种规模的问题。这将是迈阿密大学为帮助我们的研究生了解最先进的科学技术在生物学问题中的应用所做的众多努力之一。此外，其中一个促进平等委员会有几个外联方案，重点是使代表人数不足的少数群体获得研究经验，这些手段将用于实现这一目标。利用这两种仪器进行研究的影响将涵盖几个重要领域，如南佛罗里达的水管理、新陈代谢的生物医学方面、气候变化和水文学。
