MRI: Acquisition of an Isotope-Ratio Mass Spectrometer Facility for East Georgia

PIS要求提供资金，用于购买带有液体样品接口和相关的高效液相系统的双进气式轻元素同位素比质谱仪(IRMS)。所要求的仪器将补充现有的IRMS，利用三种不同的接口，为斯基达韦研究人员和外部调查人员提供一套能力。拟议的仪器将允许高精度分析大气、土壤和水样中的气体比例，并能够同时测量多种气体(氮气、氧气、Ar和二氧化碳)。高效液相系统将允许测量有机化合物中的稳定同位素，如蛋白质、RNA/DNA、碳水化合物和其他。更广泛的影响所要求的仪器将提供佐治亚州或南卡罗来纳州目前不存在的分析能力，并使学科之间能够合作。该提案指出，私营部门将在地方、地区和国家会议上促进IRMS系统的能力和使用，以促进合作和使用仪器。该中心还将向学生，包括那些代表人数不足的群体(即萨凡纳州立大学的学生)，提供关于仪器的实践培训。

The PIs request funding for the acquisition of a dual inlet, light element isotope ratio mass spectrometer (IRMS) with a liquid sample interface and associated HPLC system. The requested instrumentation would complement an existing IRMS utilizing three different interfaces to provide a suite of capabilities for Skidaway researchers and outside investigators. The proposed instrumentation would allow for the high precision analysis of gas ratios in atmospheric, soil, and aqueous samples, with the capability of measuring multiple gasses (N2, O2, Ar, and CO2) simultaneously. The HPLC system will allow for measurement of stable isotopes in organic compounds such as proteins, RNA/DNA, carbohydrates and others. Broader ImpactsThe requested instrumentation would provide analytical capabilities that do not currently exist in Georgia or South Carolina and enable collaborations among disciplines. The proposal indicates that the PIs will promote the capabilities of and access to the IRMS systems at local, regional and national meetings to promote collaborations and use of the instrumentation The center will also provide hands-on training on the instrumentation to students, including those from underrepresented groups (i.e., students from Savannah State University).
