Analysis of Amylbenzene Adsorption Equilibria on Different RP-HPLC [PDF]

Journal of Chromatographic Science, 2004
For the purpose of description of the adsorption process of amylbenzene on a C8-, C18-, and C30-bonded silica stationary phase with methanol-water (80:20, v/v) as the mobile phase, a novel adsorption model (called the cluster isotherm model) is used. The model assumes the possibility of independent adsorption of analyte clusters on the longer C30 and ...
