Abstract
The method for determining an effective Peclet number for a membrane adsorber device includes the steps of (a) equilibrating the membrane adsorber device with an equilibration buffer at a known pH and conductivity; (b) challenging the membrane with a known concentration of a specific solute in said equilibration buffer; (c) monitoring the breakthrough of the solute downstream of the membrane as a function of a value selected from the group consisting of time, challenge volume and other suitable variable related to total quantity of material challenged to membrane adsorber device; (d) analyzing the solute breakthrough curve to determine pertinent flow characteristics of said membrane adsorber device by calculating the sharpness of the breakthrough curve of the membrane adsorber device and (e) comparing the results calculated in step (d) to results from known integral devices to determine the effective Peclet number.
