近近红外光谱法结合化学计量学对有机试剂混合物进行非破坏性分析

Nondestructive analysis of mixture of organic reagents by near near-infrared spectroscopy in conjunction with chemometrics.

应用主成分分析法研究厂甲苯、丙酮和庚烷混合体系的近近红外光谱。在主成分权重图上体现了纯试剂的光谱特征。用混合休系前两个主成分的得分做图,可对混合物分类。对混合物进行目标因子分析,得到的结果与参考值一致。

The near near-infrared spectra of tolune, acetone and heptane mixtures were studied in conjunction with the method of principalcomponent analysis . The spectral characteristics of pure reagent are displayed by the plot of weight of the principal component vs wave-length. The plot drawn with the scores of the first two principal components can be used for classifying mixtures . The results of targetfactor analysis agree well with practical values .
