Example text

All these models, however, are not directly applicable to complex molecules such as proteins because separations are often operated in various conditions (pH gradients, ionic strength gradients, displacements) which induce conformational changes and therefore result in an unpredictable behavior. Models taking into account all parameters would be of too large complexity and would not be applicable to all ion exchangers. However, as a general rule ionic sites of the ion exchanger are associated with a mobile counterion of the opposite charge and can be exchanged with other small or large ions of the same charge when present in the mobile phase.

1992). For medium scale columns productivity data versus particle size showed that the use of 20–30µm particle diameter is an ideal choice. Dynamic binding capacity being higher compared to large particle diameter, the size of the column can be reduced for the same amount of protein to process; in this situation not only the resolution is better, but also the back pressure is significantly lower compared to small particle diameter, particularly with rigidly structured ion exchangers. 2 Variation of the dynamic binding capacity (DBC) of anion exchange materials as a function of the linear velocity (U).
