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.

北达科他州立大学的Andres Campiglia教授得到了分析和表面化学项目的支持，从事基础研究，探索使用低温基质进行多芳烃的光谱分析，多芳烃是环境中发现的有毒化合物。使用多种参数（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多环芳烃的复杂混合物。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。相似化合物的复杂混合物的光谱检测和鉴定是一项分析挑战。学生们将接受低温排放方法的培训，这些方法对污染地区土壤和水的快速、成本效益高的采样有潜在的重大影响。
