The application of simplex optimization to the qualitative and quantitative evaluation of chromatograms of complex mixtures is outlined. The chromatogram is considered as a linear combination of pure component chromatograms (assuming no interactions are present); if suitable components are selected

β¦ Synopsis
The principal of minimum length of a spectral trace has been used to determine the concentration of a known compound in a mixture of other unknown compounds when the unknown compounds are not available for study without the known compound mixed in with them. This method works where the spectrum of the unknown compounds approximates a quadratic curve and does not have spectral peaks in a region where there are spectral peaks of the known compound.
