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

0106605 Huang这笔赠款提供了布朗大学有机地球化学实验室购买台式气相色谱-质谱仪（GC/MS）的部分费用。 主要研究者黄永松是地质科学系的助理教授。 除了黄，其他几个学院在地质学（赫伯特，普雷尔，韦伯，克莱门斯，默里和舒尔茨）和环境研究计划（汉堡，沃德）在布朗大学将有机会获得GC/MS为他们的研究。该设施还将大大有助于实现本科生和研究生的教育目标。 增加一台台式GC/MS将使沉积物、土壤和植物样品中的有机化合物得到方便的鉴定。该仪器是有机地球化学研究各个方面的重要工具，特别是涉及特定化合物同位素分析的研究。 有机化合物的身份和纯度必须通过结构GC/MS确定，以便其同位素测量有意义。该工具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。 该补助金由地球科学仪器和设施计划（ESTA/IF）和海洋科学部（OCE）共享。

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).***
