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 ...

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 ...

IN the technique of ion-exchange chromatography, the order in which compounds are eluted from a column depends basically upon differences in their ionization constants; but other factors modify and in ...

THE importance of many carboxylic acids in metabolism makes it desirable that techniques for their estimation should, in general, be applicable to extracts of plant and animal tissues. It is essential ...

This is the third article in this series discussing HPLC oligonucleotide separations. Anion exchange chromatography can provide additional information when characterizing oligonucleotides. It can be ...
