Facilities Improvement at the Institute of Ecosystem Studies

9311411气象生态系统研究所在过去九年中研究活动的增长给分析实验室带来了越来越大的压力，需要快速处理来自各种生态系统的样品，这些生态系统的化学浓度变化了几个数量级。 该项目将通过购买新的离子色谱仪、总有机碳分析仪和高效液相色谱仪来提高分析能力。 该实验室目前为大约14个NSF支持的项目分析样品中的主要无机和有机离子。 这些项目由该机构的科学家以及外部合作者完成。 此外，该实验室还作为安德鲁W。梅隆基金会、玛丽弗拉格勒卡里慈善信托基金、美国农业部、哈德逊河基金会和其他机构。 广泛的研究生和本科生（通过NSF网站和补充REU补助金）学生的研究也在实验室完成。 该实验室目前使用的仪器型号较旧，取样能力极为有限。 有些是可操作的，但不能满足科学家的要求，因为它们要么速度慢，灵敏度有限，要么不能为样品基质提供准确的结果。 目前，其中一台（电感耦合等离子体光谱仪）只是间歇运行。 将购置的仪器将使分析实验室更有效率，并可将数据直接下载到个人电脑。 ***

9311411 Weathers Growth in research activity at the Institute of Ecosystem Studies during the past nine years has put increasing pressure on the analytical laboratory to process rapidly samples from a wide variety of ecosystems whose chemical concentrations vary by several orders-of-magnitude. This project will upgrade analytical capabilities by purchasing a new ion chromatograph, total organic carbon analyzer, and high performance liquid chromatograph. The laboratory currently analyzes samples for major inorganic and organic ions for approximately 14 NSF- supported projects. These projects are done by scientists from this institution, as well as outside collaborators. In addition, the laboratory serves as the primary analytical center for projects funded by the Andrew W. Mellon Foundation, the Mary Flagler Cary Charitable Trust, the USDA, the Hudson River Foundation and others. Extensive graduate and undergraduate (through an NSF site and supplementary REU grant) student research is also done in the laboratory. The laboratory currently operates older models of the instruments with severely limited sample capacity. Some are operational but incapable of meeting the demands of the scientists because they are either slow, have limited sensitivity, or cannot give accurate results for sample matrices. Currently, one (the inductively coupled plasma spectrometer) is only intermittently operational. The instruments to be acquired will make the analytical laboratory more efficient and allow data to be downloaded directly to a PC. ***
