Preparation, Certification and Distribution of a Reference Material for Dissolved Organic Carbon

本研究将继续参考物质计划，该计划在过去三年中为海洋化学家提供了低溶解有机碳（DOC）参考物质。 在为期三年的更新期间，PI将从马尾藻海收集深海水，制备水样，并由六个独立实验室组成的小组通过共识分析DOC。 其中两个共识实验室还将提供该DOC参比物质的总氮值。 最后，该计划计划将使该产品的用户数量增加一倍，达到全球150个实验室。 该提案的更广泛影响是为参与DOC测量的科学界提供DOC参考材料，以确保美国和国外的海洋化学家获得一致的高质量DOC浓度。

ABSTRACTOCE-0218646This study will continue the reference material program which for the last three years has made low dissolved organic carbon (DOC) reference material available to ocean chemists. During this three year renewal, the PI will collect deep ocean water from the Sargasso Sea, prepare the water samples and have the DOC analyzed via consensus by a group of six independent laboratories. Two of these consensus laboratories also will provide total nitrogen values for this DOC reference material. Lastly, this program plans to double the number of users of the product to 150 laboratories worldwide. The broader impact of this proposal is that of furnishing a DOC reference material to the scientific community involved in making DOC measurements which ensures that consistent, high quality DOC concentrations will be obtained by marine chemists both in the U.S. and abroad.
