一小部分溶解的有机物在紫外线的激发下会发出荧光。该特性用于量化和表征水生环境中溶解有机物（DOM）的变化。DOM的荧光特性的详细映射产生激发发射矩阵（EEM），这是非常适合于多路数据分析技术（化学计量学）。平行因子分析（PARAFAC）等技术越来越多地被应用于表征DOM荧光特性。在这里，介绍了该技术的优点和缺陷，其应用DOM荧光的描述。此外，一个基于MATLAB的教程和工具箱，具体到PARAFAC分析DOM荧光。
A sub-fraction of dissolved organic matter fluoresces when excited with ultraviolet light. This property is used to quantify and characterize changes in dissolved organic matter (DOM) in aquatic environments. Detailed mapping of the fluorescence properties of DOM produces excitation emission matrices (EEM), which are well suited to multi-way data analysis techniques (chemometrics). Techniques such as parallel factor analysis (PARAFAC) are increasingly being applied to characterize DOM fluorescence properties. Here, an introduction to the technique and description of the advantages and pitfalls of its application to DOM fluorescence is presented. Additionally a MATLAB based tutorial and toolbox specific to PARAFAC analysis of DOM fluorescence is presented.
