  2. Ion chromatography - Wikipedia

    en.wikipedia.org/wiki/Ion_chromatography

    Ion chromatography (or ion-exchange chromatography) is a form of chromatography that separates ions and ionizable polar molecules based on their affinity to the ion exchanger. [1] It works on almost any kind of charged molecule —including small inorganic anions, [ 2 ] large proteins , [ 3 ] small nucleotides , [ 4 ] and amino acids .

  3. Protein purification - Wikipedia

    en.wikipedia.org/wiki/Protein_purification

    Ion exchange chromatography is a very powerful tool for use in protein purification and is frequently used in both analytical and preparative separations. It is especially useful when purifying nucleic-acid binding proteins, where separation of the protein from the bound nucleic acid is required to obtain a pure sample devoid of nucleic acids ...

  4. 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.

  6. Erbium - Wikipedia

    en.wikipedia.org/wiki/Erbium

    Like other rare earths, this element is never found as a free element in nature but is found in monazite and bastnäsite ores. [9] It has historically been very difficult and expensive to separate rare earths from each other in their ores but ion-exchange chromatography methods [ 43 ] developed in the late 20th century have greatly reduced the ...

  7. Mixed-mode chromatography - Wikipedia

    en.wikipedia.org/wiki/Mixed-mode_chromatography

    In 1986, Regnier’s group synthesized a stationary phase that had characteristics of anion exchange chromatography (AEX) and hydrophobic interaction chromatography (HIC) on protein separation. [8] In 1998, a new form of MMC, hydrophobic charge induction chromatography (HCIC), was proposed by Burton and Harding.

  8. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    Ion exchange chromatography uses a charged stationary phase to separate charged compounds including anions, cations, amino acids, peptides, and proteins. In conventional methods the stationary phase is an ion-exchange resin that carries charged functional groups that interact with oppositely charged groups of the compound to retain.

  9. Hydrophilic interaction chromatography - Wikipedia

    en.wikipedia.org/wiki/Hydrophilic_interaction...

    Hydrophilic interaction chromatography (or hydrophilic interaction liquid chromatography, HILIC) [1] is a variant of normal phase liquid chromatography that partly overlaps with other chromatographic applications such as ion chromatography and reversed phase liquid chromatography.
