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

PI要求提供资金，用于购买双入口轻元素同位素比质谱仪（IRMS），该质谱仪具有液体样品接口和相关的HPLC系统。 所要求的仪器将补充现有的IRMS，利用三个不同的接口，为Skidaway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，土壤和水样品中的气体比例，同时测量多种气体（N2，O2，Ar和CO2）的能力。 HPLC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，碳水化合物等。 更广泛的影响所要求的仪器将提供格鲁吉亚或南卡罗来纳州目前不存在的分析能力，并使学科之间的合作成为可能。 该提案指出，PI将在地方、区域和国家会议上促进IRMS系统的能力和使用，以促进仪器的合作和使用。该中心还将向学生提供仪器方面的实践培训，包括来自代表性不足的群体的学生（即，来自萨凡纳州立大学的学生）。

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).
