Acquisition of a Bench-top Gas Chromatograph--Mass Spectrometer

本基金为布朗大学有机地球化学实验室购置台式气相色谱仪-质谱仪（GC/MS）的费用提供部分支持。首席研究员黄永松，地质科学系助理教授。除了Huang之外，布朗大学地质学（Herbert, Prell, Webb, Clemens， Murray和Schultz）和环境研究项目（Hamburg, Ward）的其他几个院系也可以使用GC/MS进行研究。该设施也将为本科生和研究生的教育目标做出重大贡献。增加台式GC/MS可以方便地识别沉积物，土壤和植物样品中的有机化合物。该仪器是有机地球化学研究各个方面的重要工具，特别是涉及化合物特定同位素分析的研究。为了使有机化合物的同位素测量有意义，必须通过结构GC/MS确定有机化合物的身份和纯度。该仪器还将促进布朗大学内外的研究合作。台式GC/MS将被安置在一个新装修的650平方英尺的房间里，专门设计用于容纳质谱仪和各种外围设备。该基金由地球科学仪器和设施项目（EAR/IF）和海洋科学部（OCE）共同资助

0106605HuangThis grant provides partial support of the costs of acquiring a bench-top gas chromatograph - mass spectrometer (GC/MS) for the organic geochemistry laboratory at the Brown University. The PI, Yongsong Huang is an assistant professor at Department of Geological Sciences. In addition to Huang, several other faculties at Geology (Herbert, Prell, Webb, Clemens, Murray and Schultz) and Environmental Studies Program (Hamburg, Ward) at Brown University will have access to the GC/MS for their research. This facility will also contribute significantly to the educational objectives for undergraduate and graduate students. The addition of a bench-top GC/MS will allow convenient identification of organic compounds in sediments, soils and plant samples. The instrument is an important tool for various aspects of organic geochemical research, particularly those involving compound-specific isotope analyses. The identity and purity of organic compounds must be established by structural GC/MS in order for their isotopic measurements to be meaningful. The instrument will also facilitate research collaboration in and outside Brown University. The bench-top GC/MS will be housed in a newly renovated 650 square-foot room, specifically designed to accommodate mass spectrometers and various peripheral devices. Support for this grant is shared between the Earth Sciences Instrumentation and Facilities Program (EAR/IF) and the Division of Ocean Sciences (OCE).***
