Based on the iterative target transformation of factor analysis a new algorithm for estimating the component spectra from multicomponent mixture system is developed in this paper. The method is simple and clear, and no additional restriction upon the shapes of the component spectra is necessary. The method can also be extended to the spectra resolution of n-component mixture systems without any additional difficulty. The computer simulation technique was first used to verify the algorithm, and then the practical data collected from UV spectrophotometer and fluorescence spectroscopy were also analyzed by the proposed method. Satisfactory results were obtained.
