| 摘 要： | 针对气相色谱-红外(GC-FTIR)联用的多维数据处理，提出基于盲信号分离的色谱重叠峰分离和红外吸收谱图纯化的定性定量分析方法。优点在于充分利用联用仪器提供的大量信息，解决红外和色谱分析中有机混合物无法完全分离的难题。该方法对二甲苯的同分异构体系进行了研究，验证了理论和算法的合理性，对独立分量分析的数据进行了完整的解释，讨论了针对定量分析产生误差的原因。

| Abstract: | An analysis method for separating chromatographic overlapped peaks and purifying infrared spectra is put forward, based on the blind source separation technique and the multi-dimensional data of GC-FTIR, Using various information from hyphenated instruments, this method was used to separate completely a organic mixture, the xylene isomerism system, a problem unable to solve usually. The method can confirm the rationality of theory and algorithm and give integral explanations of the independent component analysis data. The reason for the error in quantitative analysis is discussed. |
