Abstract

As already shown by the authors, the temperature-dependence of the retention index can be expressed by a first-order fractional function of the column temperature: {A figure is presented}. In the present paper, a least-squares computational method is used to determine by computer the constants to account for all the experimental variables. The equation expressing the temperature-dependence of the retention index has a shorter or longer linear portion depending on the natures of the substances involved and the stationary phase in the temperature range generally used in gas-liquid chromatography. The temperature-dependence of the retention index is significant from both the practical and the theoretical viewpoint. It has an important role in research on the structures and interactions of molecules.
