联用色谱数据的双窗口因子分析

利用组分光谱的特征信息，发展了一种能直接对联用色谱重叠峰中组分进行定性定量分析的新方法──双窗口因子分析（dualwindowfactoranalysis，DWPA）。该法可从多组分重叠峰中定性目标组分，且在未经其它组分的分辨下可直接对目标组分的光谱、色谱进行分辨。因此更适应于联用色谱对复杂体系中待测组分的定性定量分析。用该法成功地对4组分重叠峰进行了分析，实验结果令人满意。

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.
