9807023 Schoonen This grant provides 50% of the funds to replace an existing Ion Chromatograph (IC) with an automated IC equipped with UV/vis, electrochemical, and conductivity detectors for the aqueous geochemistry laboratory at the State University of New York at Stony Brook. The PI, Martin Schoonen, has been using IC for the last decade in a number of different research projects, including studies of the occurrence of metastable sulfoxyanions in (hydrothermal) waters, chloride and sulfate incorporation in sedimentary carbonates, and nitrate in groundwaters. Other users of the existing and new IC include the PI's colleagues Dr. Meyers, Reeder, Parise and Hanson in the Department of Geosciences and Drs. Taylor and Brownawell at the Marine Sciences Research Center, SUNY-SB. The new IC will be used as the main analytical tool in the PI's geochemistry lab, while the existing IC will be used for in-line analysis. The new IC provides the PI with a versatile analytical tool that can be used to determine both inorganic cations and anions as well as various organic constituents in natural waters and experimental fluids. The new IC is equipped with an autosampler and PC data acquisition package. This automation makes it possible to conduct routine analyses unattended, boosting the productivity of the PI's research group. The existing IC will be used as a dedicated in-line analyzer in experiments that require continuous monitoring. Support for the acquisition of the new IC is shared by the NSF Earth Sciences Instrumentation and Facilities Program (EAR/IF) and SUNY-Stony Brook. ***

小行星9807023 这笔赠款提供50%的资金，以取代现有的离子色谱仪（IC）与自动IC配备紫外/维斯，电化学和电导率检测器的水地球化学实验室在州立大学的纽约在斯托尼布鲁克。 PI Martin Schoonen在过去十年中一直在许多不同的研究项目中使用IC，包括研究（热液）沃茨亚稳态亚砜阴离子的出现，沉积碳酸盐中的氯化物和硫酸盐的掺入，以及地下水中的硝酸盐。 现有和新IC的其他用户包括PI的同事Meyers博士，里德，Parise和Hanson在地球科学系和Taylor博士和Brownawell在海洋科学研究中心，SUNY-SB。 新的IC将用作PI地球化学实验室的主要分析工具，而现有的IC将用于在线分析。 新的IC为PI提供了一个多功能的分析工具，可用于测定天然沃茨和实验流体中的无机阳离子和阴离子以及各种有机成分。 新的IC配备了自动进样器和PC数据采集包。 这种自动化使得无人值守的常规分析成为可能，从而提高了PI研究小组的生产力。 现有的IC将在需要连续监测的实验中用作专用的在线分析仪。 NSF地球科学仪器和设施计划（ESTA/IF）和纽约州立大学石溪分校共同支持购买新的IC。 ***
