Development of Automated Instrumentation for the Measurementof Dissolved Organic Nitrogen in Seawater, Freshwater and Soil Solutions

这是一个建议，开发一种仪器， 盐鲜中溶解有机氮（DON）的分析 沃茨和土壤的解决方案，并结合现有的 溶解有机碳分析仪（DOC），由Ionics，Inc. 这一发展将与以下方面合作进行： Ionics，Inc.是一家与我们互动了2年的公司， 1500型DOC分析仪。 在生态系统中心资助了7个主要项目和1个次要项目 在未来5年内超过10，250，000美元的水平，希望 并且需要使用DON分析仪。 项目范围从 溶解有机物的来源和生物利用的研究 河口物质对大气氮负荷的影响 温带森林的饱和度，海洋沉积物中的N循环 有机质分解、养分矿化 穿过苔原地带，沿着北极河流而下。

This is a proposal to develop an instrument for the automated analysis of dissolved organic nitrogen (DON) in salt and fresh waters and soil solutions and to couple it with an existing dissolved organic carbon analyzer (DOC) marketed by Ionics, Inc. This development will be carried out in collaboration with Ionics, Inc, a company with which we have been interacting for 2 years in refining their Model 1500 DOC analyzer. Seven major and 1 minor projects at The Ecosystems Center, funded at a level exceeding $10,250,000 over the next 5 years, want to and need to make use of a DON analyzer. Projects range from studies of the origins and biological use of dissolved organic matter in estuaries, to atmospheric loading of nitrogen and N saturation of temperate forests, to N cycling in marine sediments and to the organic matter decomposition, nutrient mineralization and transfer across the tundra landscape and down arctic rivers.
