2. Anion-exchange chromatography - Wikipedia

   en.wikipedia.org/wiki/Anion-exchange_chromatography

   Anion exchange resins will bind to negatively charged molecules, displacing the counter-ion. Anion exchange chromatography is commonly used to purify proteins , amino acids , sugars / carbohydrates and other acidic substances [ 3 ] with a negative charge at higher pH levels.

3. Ion chromatography - Wikipedia

   en.wikipedia.org/wiki/Ion_chromatography

   Cation exchange chromatography is used when the desired molecules to separate are cations and anion exchange chromatography is used to separate anions. [11] The bound molecules then can be eluted and collected using an eluant which contains anions and cations by running a higher concentration of ions through the column or by changing the pH of ...

4. Diethylaminoethyl cellulose - Wikipedia

   en.wikipedia.org/wiki/Diethylaminoethyl_cellulose

   Like all anion exchangers, the resin carries a positive charge that interacts favorably with negative charges. The positive charge of DEAE cellulose is due to a protonated amine group. To ensure that the resin is protonated and positively charged, the chromatography should be performed at least 2 pH units below the pKa of the amine group, 10.

5. Ion exchange - Wikipedia

   en.wikipedia.org/wiki/Ion_exchange

   Ion-exchange resin beads Ion-exchange column used for protein purification. Ion exchange is a reversible interchange of one species of ion present in an insoluble solid with another of like charge present in a solution surrounding the solid. Ion exchange is used in softening or demineralizing of water, purification of chemicals, and separation ...

6. Ion-exchange resin - Wikipedia

   en.wikipedia.org/wiki/Ion-exchange_resin

   Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.

7. Chromatography in blood processing - Wikipedia

   In the 1990s, the Zenalb and the CSL Albumex processes were created which incorporated chromatography with a few variations. The general approach to using chromatography for plasma fractionation for albumin is: recovery of supernatant I, delipidation, anion exchange chromatography, cation exchange chromatography, and gel filtration chromatography.

   This form of chromatography is widely used in the following applications: water purification, preconcentration of trace components, ligand-exchange chromatography, ion-exchange chromatography of proteins, high-pH anion-exchange chromatography of carbohydrates and oligosaccharides, and others.
