摘要
三维荧光光谱耦合平行因子分析技术(EEM-PARAFAC)可解析溶解性有机物结构,但目前对PARAFAC拟合组分的性质尚不了解,高分辨率质谱能从分子层级解析溶解性有机物结构;本文总结近年来三维荧光光谱技术(EEM-PARAFAC)及高分辨率质谱技术(FT-ICR-MS)用于溶解性有机物研究进展,介绍了两种技术的表征方法和应用情况,分析了两种技术的发展、联系以及目前面临的问题与挑战。
Three-dimensional fluorescence spectrometry coupled with the parallel factor analysis(EEM-PARAFAC) can be used to analyze the structure of dissolved organic compounds. However, the molecular signatures associated with PARAFAC components are poorly defined. High-resolution mass spectrometry can resolve the dissolved organic structure from the molecular level. In this paper, recent advances in three-dimensional fluorescence spectroscopy(EEM-PARAFAC) and high-resolution mass spectrometry(FT-ICR-MS) were summarized. The principles, characterization methods, and applications of the two technologies were introduced. The relationship and challenges between the two technologies were analyzed.
