title: The Influence of a Long-Chain Hydrocarbon on the Retention of Probes Differing in the Type of Intermolecular Interactions.
abstract: The surface properties of entirely hydroxylated, as well as significantly dehydroxylated, silica gel were investigated by means of the gas phase titration method. n-Tridecane was applied as blocking agent, while n-octane, benzene, and chloroform were the testing probes. The results obtained were compared to those from the previous investigation, where ethylmethylketone was used as blocking agent. After the proper recalculation of n-tridecane surface concentration it was stated that the titration curves for n-octane coincided for both blocking agents. The changes in nonspecific adsorption interaction do not depend on the type of the blocking agent intermolecular interactions. Copyright 2000 Academic Press.
