关于气相色谱中交点规律的讨论

A Note on the Intersecting Point of the Curvet of the Logarithm of Specific Retention Volume versus the Reciprocal of Temperature for Homologues in Gas Chromatography

文献[1]通过实验总结出,气相色谱中同系物各组分的比保留体积V_g对数与柱温T倒数的关系曲线之间有一共同交点,在GLC中的交点座标与固定液无关,仅取决于同系物的种类,对此称之为交点规律,并利用此规律预测同系物中各组分在不同柱温时的保留值。本文主要根据文献[2]就交点的座标和其意义提出一些看法。

The extrapolated curves of logVg versus 1/T for homologues intersect at one point in GLC but it is not always the case in GSC.ia this paper,the reasons why they behave so and the physical sense of the intersecting point are explained theoretically.
