Displacement chromatography has several advantages over the nonlinear elution technique, as well as the linear elution mode, such as the recovery of purified components at high concentrations, less tailing during elution, high throughput and high resolution. Displacer affinity and its utilization are the critical components of displacement chromatography. Particularly, the nonspecific interactions between the displacer and the stationary phase can be exploited to generate high affinity displacers. This chapter will discuss the design and execution of displacer selection and implementation in a separation specifically focusing on its utilization in ion exchange chromatography.
