Ion exchange separates components in a sample depending on their relative ionic strengths and interaction with the stationary phase. The stationary phase is a charged substance that selectively ...
Various ion-related techniques play key roles in the biopharmaceutical industry. For example, ion exchange chromatography (IEX) can be used to filter a sample, and ion chromatography (IC) can be used ...
Cation- and anion-exchange chromatography columns are used routinely for the downstream processing of therapeutic antibodies and proteins. Despite their frequent use, they are considered less ...
