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安德烈斯·坎皮格里亚教授得到了分析和表面化学计划的支持，该计划的基础研究探索使用低温矩阵对多芳烃进行光谱分析，多芳烃是环境中发现的有毒化合物。多参数(如激发波长、发射波长、荧光和磷光寿命)的使用将使分析极低浓度的多环芳烃的复杂混合物成为可能。光纤被植入到基质中以进行灵敏的检测。多芳烃是在环境中发现的剧毒化合物，例如，在炼油厂附近。对相似化合物的复杂混合物进行光谱检测和鉴定是一项分析挑战。学生将接受低温排放方法的培训，这些方法可能会对污染地区土壤和水的快速、经济有效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.
