MRI/RUI: Acquisition of a Liquid Chromatograph Ion Trap Tandem Mass Spectrometer for Chemistry Research

有了这项来自主要研究仪器（MRI）计划的奖项，查普曼大学物理科学系将获得液相色谱离子阱串联质谱仪（LC/MS）。这一设备将加强若干领域的研究，包括：（a）沿海沃茨中溶解有机物的结构特征;（B）城市气溶胶中多核芳烃的大小分布;（c）羧酸作为石油污染场地生物降解的敏感指标;（d）沿海流域城市径流人为输入的化学示踪剂。 液相色谱-质谱检测（LC/MS）是一种非常强大的技术，用于分离和分析复杂的混合物。这一工具将大大加强查普曼大学的科学研究，这是一所主要的本科院校。 这些研究将在环境科学领域产生坚实的影响。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Physical Sciences at Chapman University will acquire a liquid chromatograph ion trap tandem mass spectrometer (LC/MS). This equipment will enhance research in a number of areas including a) structural characterization of dissolved organic matter in coastal waters; b) polynuclear aromatic hydrocarbons size distribution in urban aerosols; c) carboxylic acids as sensitive indicators of biodegradation at petroleum-contaminated sites; and d) chemical tracers for anthropogenic inputs to urban runoff in a coastal watershed. Liquid chromatography with mass spectrometric detection (LC/MS) is an extremely powerful technique used for the separation and analysis of complex mixtures. This instrument will substantially strengthen scientific research at Chapman University, a primarily undergraduate institution. These studies will have a solid impact in the area of environmental sciences.
