Purchase of VG Autospec High Resolution CG/MS

杜克大学化学系将利用化学研究仪器计划和仪器和仪器开发计划的这一奖项来帮助获得质谱仪系统。此次收购将加强的化学研究领域包括：1.自由基、反应中间体和自由基生物学。2.具有重要生物学意义的低聚糖的合成与分析3.质子化碱基对、胞嘧啶脱氨基和跨链突变。4.含硼的核苷和核苷酸。5.分子隐喻和酶抑制剂。6.白石菌对环境污染物的生物降解7.环境污染物形成的有毒代谢物的鉴定。质谱学是一种用于探测大量有机、生物有机和有机金属分子的亲密结构细节和获得其分子组成的技术。当与气相色谱仪结合时，所产生的系统为化学家提供了可用于化合物分离和表征的最强大的工具之一。获得质谱计对于开展化学许多领域的前沿研究是必不可少的。

The Department of Chemistry at Duke University will use this award from the Chemistry Research Instrumentation Program and the Instrumentation and Instrument Development Program to help acquire a mass spectrometer system. The areas of chemical research that will be enhanced by the acquisition include the following: 1. Free Radical Reactive Intermediates and Free Radical Biology. 2. Synthesis and Analysis of Biologically Important Oligosaccharides. 3. Protonated Base Pairs, Cytosine Deamination, and Cross- Strand Mutagenesis. 4. Boron Containing Nucleosides and Nucleotides. 5. Molecular Metaphors and Enzyme Inhibitors. 6. Biodegradation of Environmental Contaminants Using White Rock Fungus. 7. Identification of the Toxic Metabolites Formed from Environmental Contaminants. Mass spectrometry is a technique used to probe intimate structural details and to obtain the molecular compositions of a vast array of organic, bioorganic and organometallic molecules. When combined with a gas chromatograph, the resulting system affords the chemist one of the most powerful tools available for the separation and characterization of compounds. The acquisition of a mass spectrometer is essential for the prosecution of frontier research in many fields in chemistry.
