[Dual window factor analysis for data of hyphenated chromatography].
A new method, dual window factor analysis (DWFA), used for the qualitative and quantitative analysis of target components hidden in chromatographic overlapping peaks of hyphenated methods is proposed in this paper. It's based on the characteristic information of the spectrum of the component. This method can directly be used for the qualitative analysis and the resolution of the spectrum and chromatogram of target components. Therefore, it is appropriate for the qualitative and quantitative analysis of the desired components in multicomponent complex system with hyphenated methods. DWFA is successfully applied to the analysis of the 4 components overlapping peak, and the results show that excellent correlations between resolved chromatographic peak area and mass concentration are kept in each of the 4 components.
