Abstract: Qualitative and quantitative analysis of overlapping chromatographic peaks of phenols in water is exploited with the help of the heuristic evolving latent projections (HELP) method. The results obtained show that resolved spectra of pure compounds coincide with the real spectra perfectly with their concentration ratio in the range of 1:50. The linear relationship is satisfactory in concentration range of 10-4 ~10-6 g/mL. Relative error and lowest detect limit of resolution are 5% and 3.0×10-7 g/mL, respectively.

Key words: Phenols, Two-dimension chromatographic/spectroscopy overlapping peaks, Resolution, Determination of the component number
