Fig. 7. Sensitivity analysis with respect to the thickness of the immobile phase, x_im. Observed (symbols) and simulated (four overlapping curves) colloid concentration in the effluent of Column 13. The immobile phase thickness was set to 10, 30, 60, and 100 µm, and the calibrated diffusion coefficients and C_start of the four respective simulations are given in Table 3.
