项目摘要

With this award from the Chemistry Major Research Instrumentation Program, Professor Warren De Bruyn from Chapman University and colleague Catherine Clark will acquire a benchtop spectrofluorometer with a built-in UV-VIS spectrophotometer which makes simultaneous fluorescence and absorbance measurements. The proposal is aimed at enhancing research and education at all levels, especially in areas such as studies of rates and mechanisms of photochemically driven processes and carbon cycling related to chromophoric dissolved organic matter (CDOM) in marsh, coastal and marine waters, e.g., processing and optical properties of CDOM in surface and pore waters in salt marshes, photochemical production of hydrogen peroxide in coastal waters and impacts on microbial water quality, production and decomposition of volatile organic carbon gases like acetone and photolysis of polyaromatic hydrocarbons in urban runoff.A spectrofluorometer allows fluorescence parameters. In general, fluorescence is a form of luminescence in which light is emitted by a substance that has absorbed light or other electromagnetic radiation. Often the light that is emitted has a longer wavelength and thus less energy than the absorbed radiation. This phenomenon has many useful applications in chemical sensors, fluorescence labeling, dyes and biological detectors. This instrument will be used for research and also in educational activities.

通过化学主要研究仪器计划的奖项，查普曼大学的沃伦·德·布鲁恩教授和同事凯瑟琳·克拉克（Catherine Clark）将获得带有内置UV-VIS分光光度计的台式光谱仪，可同时进行荧光和吸收测量值。该提议旨在增强各个层次的研究和教育，特别是在诸如诸如诸如有关光化学驱动的过程的速率和机制和机制以及与成熟溶解有机物（CDOR）相关的碳循环（CDOR）相关的领域，例如，沿海水域和海洋水域，例如，在盐水和孔中的CORES PRODICAL ON SALT SALT SALT SALT SALT SALT SEALTICAL ONALT CONICAL PORIDACTIC的处理和光学特性挥发性有机碳气体（如丙酮和多芳族碳氢化合物的光解）在城市径流中的光解。A频谱荧光仪可允许荧光参数。通常，荧光是一种发光的形式，其中通过吸收光或其他电磁辐射的物质发出光。通常，发射的光具有更长的波长，因此比吸收的辐射较少。该现象在化学传感器，荧光标记，染料和生物检测器中具有许多有用的应用。该工具将用于研究和教育活动。
