CRIF:MU Acquisition of a GC-TOF Mass Spectrometer with Cyber Outreach

加州大学欧文分校化学系将从化学研究仪器和设施：多用户计划(CRIF：MU)获得一台气相色谱仪飞行时间(GC-TOF)质谱仪。质谱计将促进一系列不同的研究，包括通过稀土化学和稀土元素介导的C-H活化对非极性聚合物形成的机理研究；利用过渡金属催化设计和合成具有新结构的非极性聚合物；不对称环丙化和天然产物合成；用于合成链长、多分散性和化学组成精确控制的碳氢聚合物的多元同系化反应；试剂识别碳氢化合物的合成；新的合成方法，特别是评估立体选择性；天然产物的合成，包括含氮化合物的叔丁烯族、吲哚生物碱和阿托品异构体；用于罗布酮生物合成和氧化代谢监测的合成探针；用于重复使用的水中新污染物；合成多氯代烷化学；与受体激活相关的环境污染物识别。质谱学是物理学家使用的基本工具之一，通过准确测量材料和化学物种在仪器中蒸发和破碎时的质量来识别和表征它们。它是培训年轻科学家的重要工具。近200名研究生和博士后研究人员以及研究项目的本科生使用加州大学欧文分校的质谱学设施。该设施也被荣誉化学本科生用作有机化学培训的组成部分。加州州立大学北岭分校和贡萨加大学的学生和教职员工将使用这种新仪器，他们将在自己的机构使用网络使能软件分析数据。

The Chemistry Department at the University of California- Irvine will acquire a gas chromatograph time-of-flight (GC-TOF) mass spectrometer with this award from the Chemistry Research Instrumentation and Facilities: Multi User program (CRIF:MU). The mass spectrometer will facilitate a diverse range of research including mechanistic studies on formation of non-polar polymers promulgated through lanthanide chemistry and lanthanide mediated C-H activation; design,and synthesis of nonpolar polymers with new structures utilizing transition metal catalysis; asymmetric cyclopropanation and natural product synthesis; polyhomologation reactions for synthesis of hydrocarbon polymers with precisely controlled chain length, polydispersity and chemical composition; synthesis of ant recognition hydrocarbons; new synthetic methods particularly assessing stereoselectivity; natural product synthesis involving the otellione family, indole alkaloids and atrope isomerism of nitrogen containing compounds; synthetic probes for rhodoquinone biosynthesis and for monitoring oxidative metabolism; emerging pollutants in water intended for reuse; synthetic polychlorinated alkane chemistry; environmental contaminant identification associated with receptor activation. Mass spectroscopy is one of the basic tools used by physical scientists to identify and characterize materials and chemical species by accurate measurement of their mass as they are vaporized and fragmented in the instrument. It is an essential tool in the training of young scientists. Almost 200 graduate and postdoctoral researchers as well as undergraduates in research programs use the mass spectrometry facility at UC-Irvine. The facility is also used by undergraduate classes in Honors Chemistry as a component of their training in organic chemistry. The new instrument will be used by students and faculty at California State University - Northridge and Gonzaga University who will analyze data with cyber enabling software at their home institution.
