MRI: Acquisition of a stable carbon isotope and elemental analysis system

1126128Huben这项重大研究仪器拨款支持购买激光腔衰减式光谱仪(LCRS)和元素分析仪前端燃烧装置，以支持测定沉积物、土壤、组织和天然水中碳、氢、氮、硫和氧的元素浓度和稳定的大部分有机物的碳同位素比率。所需的同位素和元素分析仪器将支持PI和学生研究，目的是确定有机质在储集层之间转化的来源和途径。研究范围从湖泊档案的古气候调查到河口底栖动物对环境变化的反应动力学。塞勒姆州立大学(SSU)是一所非授予博士学位的机构，历史上一直迎合第一代大学生。购买这种设备代表着对这所区域学院研究能力的重大基础设施增强，并将支持校园外的一些区域科学用户。

1126128HubenyThis Major Research Instrumentation grant supports acquisition a laser cavity ring-down spectrometer (LCRS) and a elemental analyzer front-end combustion device to support determination of the elemental concentrations of carbon, hydrogen, nitrogen, sulfur and oxygen and stable carbon isotope ratios of bulk organic matter in sediments, soils, tissues and natural waters. The requested isotopic and elemental analysis instrumentation would support PI and student research aimed at determining the provenance and pathways of organic matter transformation between reservoirs. Studies would range from paleoclimate investigations of lacustine archives to estuarine benthic metabolism dynamics in response to environmental changes. Salem State University (SSU) is a non-Ph.D. granting institution which historically has catered to first generation college students. Acquisition of this equipment represents a major infrastructural enhancement to the research capabilities of this regional college and will support a number of regional scientific users beyond campus.***
