MRI (RUI): Acquisition of a GC Ion Trap Tandem Mass Spectrometer for Research in Environmental Chemistry

有了这项来自主要研究仪器（MRI）计划的奖项，查普曼学院环境与化学科学系将获得一台气相色谱离子阱串联质谱仪（GCMS）。这一设备将加强若干领域的研究，包括：（a）研究湿地植物排放平流层臭氧消耗卤化化合物的速率和机制;（B）多环芳烃污染物在地表沃茨中的光化学反应;（c）利用化学示踪剂作为人为污水流入流域径流的指标的合作研究。 学院将在当地盐沼进行非点污染源的联合研究。 这项研究将被整合到四个实验室课程的研究培训GCMS技术通过学生小组项目。 气相色谱-质谱联用（GCMS）是一种非常强大的技术，用于复杂混合物的分离和分析。 该仪器将大大加强查普曼大学环境科学方面的科学研究。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Environmental and Chemical Sciences at Chapman College will acquire a gas chromatograph ion trap tandem mass spectrometer (GCMS). This equipment will enhance research in a number of areas including a) studies of emission rates and mechanisms of stratospheric ozone-depleting halogenated compounds from wetland plants; b) the photochemical reactions of polyaromatic hydrocarbon (PAH) pollutants in surface waters; and c) a collaborative study using chemical tracers as indicators for anthropogenic sewage inputs to watershed run-off. Faculty will conduct a joint ongoing study of non-point pollution sources in a local salt marsh. This study will be integrated into four laboratory courses for research training in GCMS techniques through student group projects. Gas chromatograph with mass spectrometric detection (GCMS) is an extremely powerful technique used for the separation and analysis of complex mixtures. This instrument will substantially strengthen scientific research in Environmental Sciences at Chapman University.
