With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Augustana College will acquire a gas chromatograph mass spectrometer (GC/MS). GC/MS will be used to identify and quantify decomposition products from substrate surface reactions on nanocrystalling MGO and aluminum oxide. These high surface area nanocrystalline metal oxides have shown promise at detoxifying chemical warfare agents. Other users will measure the concentrations of lead and polycyclic aromatic hydrocarbons in a nearby superfund cleanup site. GC/MS analysis will be used to monitor the reaction progress of a series of chiral spiro-aromatic compounds. Finally, direct probe MS will enable mass spectroscopic characterization of nonvolatile, higher molecular weight liquid crystals.Gas chromatograph with mass spectrometric detection (GC/MS) is an extremely powerful technique used for the separation and analysis of complex mixtures. These studies will have a tremendous impact in a number of fields, ranging from environmental sciences, to nanotechnology. The liquid crystal studies may lead to the development of electrooptical switches, piezo- and pyroelectric devices and nonlinear optics in addition to liquid crystal displays. In addition, undergraduates will have hands-on experience in a number of newly developed courses at Augustana College.

凭借重大研究仪器 (MRI) 计划的这一奖项，奥古斯塔纳学院化学系将获得一台气相色谱质谱仪 (GC/MS)。 GC/MS 将用于识别和量化纳米晶 MGO 和氧化铝基材表面反应的分解产物。 这些高表面积纳米晶金属氧化物在化学战剂解毒方面显示出前景。 其他用户将测量附近超级基金清理场地中铅和多环芳烃的浓度。 GC/MS 分析将用于监测一系列手性螺芳香族化合物的反应进程。 最后，直接探针 MS 将能够对非挥发性高分子量液晶进行质谱表征。具有质谱检测功能的气相色谱仪 (GC/MS) 是一种用于分离和分析复杂混合物的极其强大的技术。这些研究将对从环境科学到纳米技术等许多领域产生巨大影响。 除了液晶显示器之外，液晶研究还可能促进电光开关、压电和热电器件以及非线性光学的发展。 此外，本科生还将获得奥古斯塔纳学院许多新开发的课程的实践经验。
