【Abstract】 Resolution and determination of complex isomer system: 2,3-dimethylphenol, 2,4-dimethylphenol, 2,5-dimethylphenol, 2,6-dimethylphenol, 3,4-dimethylphenol of serious overlapped chromatograms and spectra were studied. Before the system was resolved by alternating trilinear decomposition (ATLD) algorithm, the better region of the chromatograms and spectra was selected purposely. The complex system was simultaneously determined among the five dimethylphenol isomers, and satisfactory results were obtained.更多还原
