气相色谱中,由于非极性固定液对大多数有机化合物具有良好的分离效能,且由于在该类固定液上溶质的保留值与溶质的物化参数间存在着简单的关系,而使这类固定液得到了广泛的应用。分离效能好可使我们用较少的柱子解决较多的分析问题;保留值与溶质的物化参数间关系简单,则使我们从理论上预测保留值成为可能。然而极性物质在此类固定液上保留数据的非重现性就使这些数据损失了定性价值。保留数据的非重现性
In gas chromatography, non-polar fixatives have good separation performance for most organic compounds and because of the simple relationship between the retention of solutes on this fixative and the solute physico-chemical parameters, Liquid has been widely used. Separation efficiency allows us to use fewer columns to solve more analytical problems; retention and solute physical and chemical parameters of the relationship between the simple, then allow us to predict the value of the theory possible. However, the non-reproducibility of polar data retention on such fixatives discourages these data from qualitative value. Retain the non-reproducibility of the data
