Spectrophotometry in combination with chemometric algorithms can be applied for the analysis of mixtures with similar spectral characteristics. The methods of multiple linear regression are recommended to use in analysis of 2 or 3 component mixtures, with the increasing number of analytes it is advisable to use the method of projection to latent structures (PLS). The optimum amount of training samples to construct the PLS - calibration which can determine the components with errors of less than 10-15% was established.Keywords: method of multiple linear regression, method of projection to latent structures, similar absorption spectra(Russian)DOI: http://dx.doi.org/10.15826/analitika.2013.17.3.010P.A.
