Experimental methods Taylor dispersion

The chemical diffusion coefficient is a phase property where the reference velocity is chosen in the Fick reference system. Various methods are known for the experimental determination of chemical diffusion coefficients, such as open and closed capillary methods, dynamic light scattering, or the Taylor dispersion method. 

The theory of the Taylor dispersion technique is well described in the literature [11-20], and so the authors only indicate some relevant points concerning this method on the experimental determination of binary and ternary diffusion coefficients (Figure 2).
