✦ Synopsis

Gas chromatographic net retention data of a number of mono-substituted alkane and benzene derivatives on trimethyIsiIy1, octadecyIsiIy1 (ODS) and trimethylchlorosilane treated ODS Porasil C have been measured at 160" and interpreted in terms of the adsorption model of Snyder. On the basis of plausible assumptions, the interaction of apolar samples with the ODS chains is separated from that with the adsorbent surface underneath. For polar samples, the effects of these two interaction mechanisms cannot be distinguished.
