MRI: Acquisition of a Time-of-Flight GC-Mass Spectrometer

该奖项由2009年美国复苏和再投资法案(公法111-5)资助。西北大学化学系将获得一台用于教学和研究的气相色谱仪飞行时间(GC-TOF)质谱仪。将研究各种研究项目，包括：1)有机f元素化学-综合合成、机理、催化和热化学研究；2)基于超分子配位组装的酶模拟物；3)为动态过程打造的网状网络；4)释放N-烯丙基肼的合成潜力；以及5)分子自旋。质谱学(MS)用于鉴定样品的化学成分，并通过测量样品中的分子组分的质量来确定其纯度。层析是一种分离技术，它先于质谱分析。它将混合物分离成其组成的化学物质，然后由质谱仪进行分析。这些分析技术被广泛用于表征样品的化学成分。质谱仪将被本科生和研究生使用，并在本科生的实验室课堂上使用。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Major Research Instrumentation (MRI) program, the Chemistry Department at Northwestern University will acquire a gas chromatograph time-of-flight (GC-TOF) mass spectrometer for use in teaching and research. A variety of research projects will be investigated including: 1) Organo-f-Element Chemistry - Integrated Synthetic, Mechanistic, Catalytic, and Thermochemical Studies; 2) Enzyme Mimics Based on Supramolecular Coordination Assembly; 3) Reticular Networks Forged for Dynamic Processes; 4) Unlocking the Synthetic Potential of N-Allylhydrazones; and, 5) Molecular Spintronics.Mass spectrometry (MS) is used to identify the chemical composition of a sample and determine its purity by measuring the mass of the molecular constituents in the sample after they are ionized and detected by the mass spectrometer. Chromatography is an isolation technique that precedes the mass spectrometry analysis. It separates a mixture into its constituent chemicals which are then analyzed by the mass spectrometer. These are analytical techniques widely used to characterize the chemical composition of a sample. The mass spectrometer will be used by undergraduate and graduate research students and in undergraduate laboratory classes.
