    en.wikipedia.org/wiki/List_of_purification...

    Chromatography employs continuous adsorption and desorption on a packed bed of a solid to purify multiple components of a single feed stream. In a laboratory setting, mixture of dissolved materials are typically fed using a solvent into a column packed with an appropriate adsorbent, and due to different affinities for solvent (moving phase ...

  4. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    Liquid chromatography (LC) is a separation technique in which the mobile phase is a liquid. It can be carried out either in a column or a plane. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high-performance liquid chromatography.

  5. Selected reaction monitoring - Wikipedia

    en.wikipedia.org/wiki/Selected_reaction_monitoring

    This experiment can be performed on triple quadrupole mass spectrometers, where mass-resolving Q 1 isolates the precursor, q 2 acts as a collision cell, and mass-resolving Q 3 is cycled through the product ions which are detected upon exiting the last quadrupole by an electron multiplier. A precursor/product pair is often referred to as a ...

  6. Gel permeation chromatography - Wikipedia

    en.wikipedia.org/wiki/Gel_permeation_chromatography

    Gel permeation chromatography (GPC) [1] is a type of size-exclusion chromatography (SEC), that separates high molecular weight or colloidal analytes on the basis of size or diameter, typically in organic solvents. The technique is often used for the analysis of polymers.

  7. Chiral column chromatography - Wikipedia

    en.wikipedia.org/wiki/Chiral_column_chromatography

    The chiral stationary phase, CSP, can interact differently with two enantiomers, by a process known as chiral recognition. Chiral recognition depends on various interactions such as hydrogen bonding, π-π interaction, dipole stacking, inclusion complexation, steric, hydrophobic and electrostatic interaction, charge-transfer interactions, ionic interactions etc, between the analyte and the CSP ...

  8. Chromatography column - Wikipedia

    en.wikipedia.org/wiki/Chromatography_column

    Small scale chromatography columns are mostly intended for design of experiments (DoE); proof of concept; validation (drug manufacture) or research and development experiments. Columns of this scale category are distinguished by their small dimensions in comparison to chromatography columns intended for larger scales as well as relatively high ...

  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.
