Van Deemter's equation for this process accounts for Eddy-diffusion and mass transfer, and the Kovats index describes the time taken for one form of this process.
Van Deemter's equation for this process accounts for Eddy-diffusion and mass transfer, and the Kovats index describes the time taken for one form of this process. Another form of this process uses high pressures to improve performance. The extent of the solvent front is used to calculate the retardation factor in the thin-layer form of this technique. Often performed in a silica-packed column, it involves mobile and stationary phases. A common demonstration of it involves using filter paper strips to separate pigments. For 10 points, name this group of techniques for separating mixtures.
