根据色谱峰面积、校正因子和待测组分含量的关系，应用Ｌｅｖｅｎｂｅｒｇ－Ｍａｒｑｕａｒｄｔ方法对气相色谱分析数据进行最优化计算，可在缺乏待测组分标准样品的条件下测定相应的校正因子。分别测定了甲苯－氯苯、二乙氧基甲烷－乙酸乙酯和二乙氧基甲烷－乙醇－水等３个体系中各组分的相对校正因子。结果表明：化合物校正因子的测定值与相应文献值的相对偏差小于３％。根据实验结果进一步讨论了方法的适用范围以及进行测定所需样品的数目。
According to the chromatographic peak area, the correction factor and the content of the components to be tested, the Levenberg-Marquardt method was used to optimize the gas chromatographic data to determine the corresponding calibration factors in the absence of standard samples. The relative correction factors of each component in toluene-chlorobenzene, diethoxymethane-ethyl acetate and diethoxymethane-ethanol-water were determined respectively. The results show that the relative deviation between the measured value of compound correction factor and the corresponding literature value is less than 3%. Based on the experimental results, the scope of the method and the number of samples required for the determination are further discussed.
