Chromatographic evaluation of sorption and diffusion characteristics of glucose, maltose and maltotriose in silica gels

Abstract

Liquid chromatographic techniques were employed to evaluate the sorption and diffusion characteristics of glucose, maltose and maltotriose in silica gel. The equilibrium constants were found to decrease with increasing molecular size. The determined diffusion coefficient of glucose is comparable to that in the literature. The pore diffusivities decrease with increasing size of the carbohydrates at all temperatures.
