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.

通过主要研究工具（MRI）计划的奖项，查普曼大学的物理科学系将获得液相色谱离子陷阱串联质谱仪（LC/MS）。该设备将增强许多领域的研究，包括a）沿海水域中溶解有机物的结构表征； b）城市气溶胶中的多核芳烃大小分布； c）羧酸作为石油污染位点生物降解的敏感指标； d）沿海流域中城市径流的人为输入的化学示踪剂。 具有质谱检测（LC/MS）的液相色谱法是一种非常强大的技术，用于分离和分析复杂混合物。该工具将大大加强主要是本科机构查普曼大学的科学研究。 这些研究将对环境科学领域产生牢固的影响。
