从收集的许多气相色谱法分离低级烃类的资料可以看出,在极性或非极性色谱柱上,烃类的流出次序都有一定的规律性。把这些规律性与分子间的作用力联系起来,就会发现,除个别组份外,烃类在色谱柱上的流出次序大体上同各组份与固定相分子间的作用力的大小相吻合。由此可见,深入探讨分子间的作用力是研究色谱分离技术的一个重要途径。 Separation of lower hydrocarbons from many of the collected GC data shows that there is a regular pattern of hydrocarbon outflow on polar or non-polar columns. By linking these regularities to the intermolecular forces, it is found that, with the exception of individual components, the hydrocarbon outflow order on the column generally corresponds to the magnitude of the force between the components and the stationary phase molecules . Thus, in-depth discussion of the interaction between molecules is an important way to study chromatographic separation techniques.
