The effect of the structure and structural changes of the stationary phase on the retention characteristics of solutes. I. The study of interactions in solutions

Interactions between n-octadecane and its monofunctional derivatives (1-chloro-, 1-hydroxy-), used as stationary phases, and solutes of various structural types have been studied. Using open tubular columns, ensuring a high separation efficiency and relative inertness of the inner surface, the retention data were measured and from them the specific retention volumes, the retention indexes, and the differential solution heats were calculated. Correlations between the measured quantities and the structures of both the stationary phases and the solutes are discussed.
