| Abstract: | A new chemometrics algorithm of spectral multivariate analysis has been developed for systems containing unknown interfering components. The algorithm is based on matrix projection procedure and minimum entropy concept. No reference spectra of possible interferences from the library is required. Good results with visible absorption spectra of metal-ion mixtures and fluorescence spectra of mixtures of polycyclic aromatic compounds demonstrate the effectiveness of the method. |
