MRI: Acquisition of Total Organic Carbon/Total Nitrogen Analyzer for Interdisciplinary Research and Teaching at Georgia Gwinnett College

该奖项由重大研究仪器(MRI)和化学仪器P(CRIF)计划支持。乔治亚州格温尼特学院的伊丽莎白·苏达斯教授及其同事李承进和桑H·帕克已经获得了一台总有机碳/总氮分析仪。该仪器使用了一种历史悠久的分析技术，这是分析样品的基础。这是一种燃烧分析，通过燃烧(燃烧或氧化)样品可以提供碳和氮等元素的含量。这是对水或水处理中的材料进行环境分析的基本分析工具。即将进行的研究主要集中在佐治亚州地区。它为本科生提供测量、数据分析和仪器使用方面的培训，为他们未来的技术工作或更高水平的培训提供有价值的培训。授予这一分析器的目的是加强各级的研究和教育。它特别有助于描述城市化和海狸活动对城市溪流中有机碳和氮浓度模式以及生态系统功能的影响。该仪器是评估地表水处理效率和可持续营养循环工艺的必要工具，用于调查格温尼特县饮用水水源地的含氮消毒副产物形成潜力。该分析仪还帮助研究人员和学生表征大气气溶胶的组成和氮气的干大气沉积率，以及使用在校园内合成的商用超低硫柴油和生物柴油的燃料混合物来表征柴油发电机的燃烧废气。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award is supported by the Major Research Instrumentation (MRI) and Chemical Instrumentation P(CRIF) programs. Professor Elizabeth Sudduth from Georgia Gwinnett College and colleagues Seungjin Lee and Sang H Park have acquired a total organic carbon/total nitrogen analyzer. This instrument uses an analysis technique that is historic and fundamental to analyzing samples. This is combustion analysis which by combusting (burning or oxidizing) a sample can provide the content of elements such as carbon and nitrogen. This a basic analytical tool for environmental analysis of materials in water, or water treatment. The research to be conducted is largely localized to the Georgia region. It provides undergraduate students training in measurement, data analysis, and instrumentation usage valuable as they go on to future technical employment or to higher level training. The award of this analyzer is aimed at enhancing research and education at all levels. It especially aids the characterization of the effects of urbanization and beaver activity on patterns in organic carbon and nitrogen concentrations and ecosystem functions in urban streams. The instrument is necessary for the evaluation of the efficiency of surface water treatment and recycling processes for sustainable nutrients for the investigation of nitrogenous disinfection byproducts formation potential of Gwinnett County's drinking water source. The analyzer also helps investigators and students in characterizing the composition of atmospheric aerosols and dry atmospheric deposition rates of nitrogen, and for the characterization of combustion exhaust gas from a diesel generator using fuel blends of commercial ultra-low sulfur diesel and biodiesel synthesized on campus.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
