Measurement of diffusion coefficients in gel beads: Random and systematic errors

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

The method of calculating diffusion coefficients in gel beads based on transient experiments of solute uptake from a finite volume has been studied theoretically. Monte Carlo simulation was used to investigate the effect of random errors in the concentration measurements. The influence of sampling frequency and diffusion direction was investigated. Systematic errors derived from an assumption of constant diffusion coefficient and of monodisperse beads were also investigated.
