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

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。有了来自主要研究仪器（MRI）计划的这一奖项，西北大学化学系将获得一台气相色谱飞行时间（GC-TOF）质谱仪，用于教学和研究。将研究的各种研究项目包括：1）有机元素化学-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）动态过程的网状网络锻造; 4）解锁N-烯丙基腙的合成潜力;和5）分子自旋电子学质谱（MS）用于鉴定样品的化学组成，并通过在样品中的分子成分被电离并由质谱仪检测之后测量它们的质量来确定其纯度。 色谱法是一种先于质谱分析的分离技术。 它将混合物分离成其组成化学物质，然后由质谱仪进行分析。 这些是广泛用于表征样品化学成分的分析技术。 质谱仪将用于本科生和研究生的研究生和本科实验室课程。

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.
