Purchase of a Departmental Gas Chromatograph/Mass Spectrometer (GC/MS) System

化学研究仪器项目的这一奖项将帮助怀俄明大学化学系购买气相色谱-质谱仪(GC-MS)。这种新的仪器将极大地加强以下领域的研究：1)囊泡双层性质的立体化学依赖性，2)金属卟啉氧和亚硝基配合物的仿生氧化：对精氨酸生物合成一氧化氮的合理理解，3)有机硫化物的光化学氧化，4)羰基-Lewis酸配合物的反应几何构型，5)聚合物/金属电极电催化CO2还原成烃的机理和制备研究。气相色谱/质谱仪(GC/MS)用于分离反应混合物中的分子，测量存在的各种分子的相对数量，并获得有关存在的分子的分子质量的信息。该仪器对现代化学合成的研究工作是必不可少的。

This award from the Chemistry Research Instrumentation Program will assist the Department of Chemistry at the University of Wyoming in the purchase of a Gas Chromatograph Mass Spectrometer (GC-MS). This new instrumentation will enhance greatly research in a number of areas including the following: 1) Sterochemical dependence of vesicle bilayer properties, 2) Biomimetic oxidation of guanidines by metalloporphyrin oxo and nitrosyl complexes: Toward a rational understanding of the biosynthesis of nitric oxide from arginine, 3) Photochemical oxidation of organic sulfides, 4) Reactive geometries of carbonyl-Lewis acid complexes, 5) Mechanistic and preparative studies of the electrocatalytic reduction of CO2 to hydrocarbons using polymer/metal electrodes. %%% The gas chromatograph mass spectrometer (GC/MS) is used to separate the molecules in a reaction mixture, to measure the relative amounts of the various molecules present and to obtain information about the molecular weight of the molecules present. This instrument is essential for research work in modern chemical synthesis.
