Study Notes
Ion Exchange Chromatography
- Ion exchange is the term used to describe the process when ions are exchanged from the liquid to the resin.
Anion Exchangers
- Quaternary ammonium groups are covalently bound to the packing in anion exchangers.
Cation Exchangers
- Cation exchangers are designed to bind positively charged ions (cations).
Regeneration Step
- The purpose of the regeneration step in ion exchange chromatography is to remove the bounded ions and reactivate the resin.
Ion Exchange Resins
- Using methacrylic acid instead of styrene in the polymerization process for ion exchange resins results in resins with different properties.
