Abstract：The technique of fluorescence spectrum is one of the efficient methods for monitoring and identifying dissolved organic matter, oil pollutants and biomass of phytoplankton in water. A new kind of fluorescence spectrum system with a multi-wavelength LED array as the exciting light source is introduced. The principle of the system and the method for multi-component analysis are discussed. The excitation-emission matrix (EEM) fluorescence spectra of samples mixed with different concentration fluorescent dyes were measured with this system in the authors’ laboratory, which were analyzed using parallel factor (PARAFAC) algorithm. The results indicate that the correlation coefficient of the resolved concentration and actual ones is up to 98%, which shows the potential application of the fluorescence spectrum system in multi-component analysis.
