Abstract
Abstract The combined effects of pH (3.6–6.0) and octylamine hydrochloride concenttration (0–5.0 mM) in methanol—water (20:80) eluents were determined for hydrocinnamic, trans-cinnamic, phenylacetic, trans-p-coumaric, trans-ferulic, trans-caffeic and vanillic acids; for phenylethylamine; and for phenylalanine. The effects are described by a simple ion-interaction model that does not require ion-pair formation in either phase and is not based upon classical ion exchange. The simplicity and generality of the mathematical forms of the model make it useful for predicting retention behavior.
