✦ Synopsis

A method is described for the determination of the content of the liquid phase in packings for gas-liquid chromatography.

It is shown that the extraction method is subject to an error due to the solubility of some inorganic compounds of the support.

A more satisfactory method involves the evaporation of the stationary phase and an accuracy of O.OS-O.lO~O is obtained. It is necessary, however, to apply a correction for the weight loss of the pure support at the same temperature.
