Novel Instrumentation and Experimental for Absorption and Multidimensional Luminescence Spectroscopy at Liquid Nitrogen and Helium Temperatures

北达科他州州立大学的Andres Campiglia教授得到了分析和表面化学项目的支持，进行基础研究，探索使用低温基质对环境中发现的有毒化合物多环芳烃进行光谱分析。 使用多个参数（例如激发波长、发射波长、荧光和磷光寿命）将允许在非常低的浓度下分析PAH的复杂混合物。 在基质中植入一根光纤，用于灵敏的检测。多芳烃是一种在环境中发现的剧毒化合物，例如在炼油厂附近。 光谱检测和识别非常相似的化合物的复杂混合物是一项分析挑战。 学生将接受低温排放方法的培训，这些方法可能对污染地区土壤和水的快速、成本效益高的采样产生重大影响。

Professor Andres Campiglia of North Dakota State University is supported by the Analytical and Surface Chemistry Program for fundamental studies exploring the use of low temperature matrices for the spectroanalysis of polyaromatic hydrocarbons, which are toxic compounds found in the environment. The use of multiple parameters (e.g. excitation wavelength, emission wavelength, fluorescence and phosphorescence lifetime) will allow the analysis of complex mixtures of PAH's at very low concentrations. A fiberoptic is implanted in the matrix itself for sensitive detection.Polyaromatic hydrocarbons are extremely toxic compounds found in the environment, near oil refineries, for example. The spectroscopic detection and identification of complex mixtures of closely resembling compounds is an analytical challenge. Students will be trained in methods of low temperature emission methods that have the potential for significant impact in the rapid, cost-effective sampling of soils and water in polluted areas.
