Centrifuges are often used in countercurrent varieties of it, and size exclusion and ion exchange are among the high performance liquid type of this technique.
In one variety of this process, proteins are tagged with polyhistidine and glutathione-s-transferase. Eddy diffusion and mass transfer are related in Van Deemter's equation for this technique.  Centrifuges are often used in countercurrent varieties of it, and size exclusion and ion exchange are among the high performance liquid type of this technique. Kovat's index of retention times is used to compare relative elution times in one type. For 10 points, name this technique which comes in column, planar, gas, and  liquid varieties and is used to separate mixtures of stationary and mobile phases.
