The retention behaviour of alkyl-and dialkylphenols has been investigated by gas-liquid chromatography (GLC) on glass capillary columns, coated with PS-255 and OV-1701-Vi, and by gas-solid chromatography (GSC) on a microcolumn, packed with uncoated graphitized thermal carbon black (GTCB). The depend

✦ Synopsis
A new graphical method is proposed for estimating the retention mechanism in gas-liquid partition chromatographic (GLPC) systems in which adsorption phenomena occur. The proposed method enables the adsorption phenomena accompanying the bulk liquid solution to be investigated unequivocally from gas chromatographic data alone. Moreover, it can be applied even in the very complicated instances of the GLPC systems with heterogeneous, and in addition not totally loaded, support surfaces. The utility of this method is demonstrated for two different GLPC systems with strong adsorption properties.
