气相色谱灰色分析体系中未知组分保留指数的预测

Abstract：In order to obtain the retention indices of unknown components in gas chromatography, a method using retention indices and retention times of known components to calculate the dead time and retention times of the corresponding normal alkanes was developed. The results showed that the estimation of the dead time and the retention times of the normal alkanes and the further prediction of the retention indices of unknown components were quite satisfactory when the number of the known components included in calculation was not too small.
Keywords：Retention indices, grey multicomponent system, gas chromatography, multiple linear regression
