Abstract:: To whom correspondence should be directed.Chromatography of basic solutes has been described on non-modified silica and alumina using aqueous buffers with suitable modifiers. On these packing materials selectivity and retention of the compounds are influenced in various ways; by the modifier content, the electrolyte concentration and the pH. Generally, only cationic species are retained on these sorbents. Their retention decreases with increasing electrolyte concentration. The relationship between retention … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
