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.
Test your knowledge of ion-exchange chromatography with this quiz. Explore the principles of reversible ion exchange between solids and liquids and the structure of stationary phases. Familiarize yourself with anion and cation exchangers and their charged groups.
