Application Note: Prediction of the impact of buffer type with mechanistic simulation

Application to protein purification by IEX chromatography
The proper selection of buffers is essential in the design of ion exchange processes. It was reported that at a given pH and ionic strength, a change in the type of buffer (e.g., acetate to phosphate) may have a dramatic impact on protein separation...
