MRI: Acquisition of a Linear Ion Trap Mass Spectrometer

凭借这项由主要研究仪器（MRI）计划和化学部颁发的奖项，Alexandra C. Stenson和他的同事Norris W.作者：霍夫曼Davis和Scott A. 来自南亚拉巴马大学的米勒将获得一台离子阱质谱仪。 该工具将加强研究工作：a）在具有地质和海洋化学重要性的天然化合物的结构表征方面取得进展，B）改进和增强离子液体对CO2的捕获，c）开发扩大的爆炸物的乘客和货物筛选能力，d）通过分析遗留的有机残留物来确定古代陶器的原始用途，e）改进当前的合成催化剂并开发新的催化剂，f）开发新的药物支架/为新的药物支架奠定基础，g）帮助监管农业用途的昆虫诱饵和陷阱，以及，h）提高普通HPLC柱的选择性和/或提高该选择性的可预测性。用于通过测量样品中的分子成分在它们被电离并被质谱仪检测之后的质量来识别样品的化学成分。离子阱是用于质量分析器的特殊设计，其分离离子以供随后在检测器处识别。 大学几个系的本科生将接受这种广泛使用的分析技术的培训，因为他们在研究项目和实验室课程中使用这种技术。

With this award from the Major Research Instrumentation (MRI) program and the Chemistry Division, Alexandra C. Stenson and colleagues Norris W. Hoffman, James H. Davis and Scott A. Miller from University of South Alabama will acquire an ion trap mass spectrometer. The instrument will enhance research efforts: a) to make in-roads in the structural characterization of natural compounds of geo and marine chemical importance, b) to improve and enhance CO2 capture by ionic liquids, c) to develop expanded passenger- and cargo-screening capabilities for explosives, d) to determine the original use for ancient pottery through analysis of organic residues left behind, e) to improve current synthetic catalysts and develop new ones, f) to develop/lay the groundwork for new pharmaceutical scaffolds, g) to aid the regulation of insect lures and traps for agricultural use, and, h) to improve selectivity in common HPLC columns and/or enhance the predictability of this selectivity.Mass spectrometers (MS) are used to identify the chemical composition of a sample by measuring the mass of the molecular constituents in the sample after they are ionized and detected by the mass spectrometer. The ion trap is a particular design for the mass analyzer that separates the ions for subsequent identification at the detector. Undergraduates in several departments at the University will be trained in this widely employed analysis technique as they use it in their research projects and in laboratory courses.
