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

这笔赠款为布朗大学的有机地球化学实验室购买台式气相色谱-质谱仪(GC/MS)提供了部分支持。黄永松是地质科学系的助理教授。除了黄，布朗大学地质学(赫伯特、普雷尔、韦伯、克莱门斯、默里和舒尔茨)和环境研究项目(沃德汉堡)的其他几个学院将可以使用GC/MS进行他们的研究。这一设施还将极大地促进本科生和研究生的教育目标。增加了台式GC/MS，可以方便地鉴定沉积物、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那些方面。有机化合物的同一性和纯度必须通过结构GC/MS确定，才能使其同位素测量有意义。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，专门为容纳质谱仪和各种外围设备而设计。对这笔赠款的支持由地球科学仪器和设施方案(EAR/IF)和海洋科学司(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).***
