项目摘要
The instrumentation project focuses on the purchase of an isotope ratio mass spectrometer with a gas chromatographic front end. Specifically the proposal request will customize a new gas source isotope ratio mass spectrometer with a gas chromatographic inlet (GC-IRMS) for measurement of the stable isotopes of nitrate and nitrous oxide. Technological advances in analytical chemistry and instrumentation over the last several decades improved the sensitivity and precision of these measurements, which in turn expanded the understanding of the nitrogen biogeochemical cycles. The environmental properties of the N cycle are in turn key to the health of global agriculture, extra-terrestrial ecology and marine productivity. Acquisition of a customized GC-IRMS will allow more and improved stable isotope measurements to be made at URI. Recent technological advances provide enhanced sensitivity and precision, up to a 3-fold improvement from current capabilities. This should allow researchers to address questions on samples with limited availability for analysis or that require greater precision, or both.The enhanced isotope infrastructure and expertise at GSO will attract talented new students, postdocs, and faculty to GSO, providing them with marketable skills in cutting edge analytical techniques. This will in turn facilitate improved training opportunities that promote diversity and inclusion in STEM fields.Characteristics of this proposal that align with MRI and EPSCoR co-funding guidelines include: collaboration with researchers at other universities in the US and abroad; provides instrumentation for stable isotope research education; integration of research and education through training opportunities for students and incorporation in college courses.This project is jointly funded by Antarctic Sciences, Office of Polar Programs (OPP), by the Established Program to Stimulate Competitive Research (EPSCoR), and MRI, the Major Instrumentation Research Program.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.
仪器项目的重点是购买具有气相色谱前端的同位素比率质谱仪。 具体的提案请求将定制带有气相色谱入口(GC-IRNS)的新气体同位素比率质谱仪,以测量硝酸盐和一氧化二氮的稳定同位素。在过去的几十年中,分析化学和仪器的技术进步提高了这些测量值的敏感性和精度,从而扩大了对氮生物地球化学周期的理解。 n周期的环境特性又是全球农业,周期生态学和海洋生产力的健康的关键。 获取定制的GC-IRMS将允许在URI上进行更多和改进的稳定同位素测量。最近的技术进步提供了增强的灵敏度和精度,与当前能力相比最大提高了3倍。这应该使研究人员能够解决有关分析可用性有限或需要更高精度或两者兼而有之的样本问题的问题。增强的同位素基础架构和GSO的专业知识将吸引有才华的新学生,博士后和教职员工到GSO,从而为他们提供了廉价的最先进分析技术的销售技能。反过来,这将有助于改善培训机会,从而促进STEM领域的多样性和包容性。与MRI和EPSCOR共同资助指南保持一致的该提案的特征包括:与美国和国外其他大学的研究人员的合作;为稳定的同位素研究教育提供仪器;通过为学生提供培训机会并在大学课程中成立研究和教育的整合。该项目由南极科学,极地计划办公室(OPP),既定的刺激竞争性研究(EPSCOR)的计划共同资助,而MRI(EPSCOR)和MRI(主要的仪器研究计划)是NSF的法定任务和审查局长的范围。
