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.

查普曼大学物理科学系将从主要研究仪器(MRI)计划获得这一奖项，并将获得一台液体色谱仪离子陷阱串联质谱仪(LC/MS)。该设备将加强若干领域的研究，包括：(A)沿海水域溶解有机物的结构特征；(B)城市气溶胶中多环芳香烃的粒度分布；(C)作为石油污染地点生物降解敏感指标的羧酸；以及(D)沿海流域城市径流人为输入的化学示踪剂。液质联用(LC/MS)是一种用于复杂混合物分离和分析的非常有效的技术。这一仪器将大大加强查普曼大学的科学研究，查普曼大学主要是一所本科院校。这些研究将在环境科学领域产生坚实的影响。
