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）中获得一台气相色谱仪飞行时间（GC-TOF）质谱仪。质谱仪将促进各种各样的研究，包括通过镧系化学和镧系介导的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新结构的非极性聚合物；不对称环丙烷化与天然产物合成合成具有精确控制链长、多分散性和化学成分的烃类聚合物的多同源反应；蚂蚁识别烃类化合物的合成新的合成方法，特别是评价立体选择性的方法；天然产物的合成涉及欧特利酮家族、吲哚类生物碱和含氮化合物的欧洲异构体；红醌生物合成及氧化代谢监测探针用于再利用的水中新出现的污染物；合成多氯烷烃化学；与受体激活相关的环境污染物识别。质谱是物理科学家用来识别和表征物质和化学物质的基本工具之一，通过精确测量它们在仪器中蒸发和破碎的质量。它是培养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分析设备。该设施也被荣誉化学本科班用作有机化学培训的组成部分。新仪器将由加州州立大学北岭分校和冈萨加大学的学生和教师使用，他们将在自己的学校使用网络启用软件分析数据。

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.
