  2. High-performance liquid chromatography - Wikipedia

    en.wikipedia.org/wiki/High-performance_liquid...

    HPLC has many applications in both laboratory and clinical science. It is a common technique used in pharmaceutical development, as it is a dependable way to obtain and ensure product purity. [59] While HPLC can produce extremely high quality (pure) products, it is not always the primary method used in the production of bulk drug materials. [60]

  3. Monolithic HPLC column - Wikipedia

    en.wikipedia.org/wiki/Monolithic_HPLC_column

    A monolithic HPLC column, or monolithic column, is a column used in high-performance liquid chromatography (HPLC). The internal structure of the monolithic column is created in such a way that many channels form inside the column.

  4. Chromatography column - Wikipedia

    en.wikipedia.org/wiki/Chromatography_column

    A chromatography column is a device used in chromatography for the separation of chemical compounds. A chromatography column contains the stationary phase , allowing the mobile phase to pass through it.

  5. Reversed-phase chromatography - Wikipedia

    en.wikipedia.org/wiki/Reversed-phase_chromatography

    Silica gel particles are commonly used as a stationary phase in high-performance liquid chromatography (HPLC) for several reasons, [13] [14] including: High surface area: Silica gel particles have a high surface area, allowing direct interactions with solutes or after bonding of variety of ligands for versatile interactions with the sample molecules, leading to better separations.

  6. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    In HPLC the sample is forced by a liquid at high pressure (the mobile phase) through a column that is packed with a stationary phase composed of irregularly or spherically shaped particles, a porous monolithic layer, or a porous membrane.

  7. Column chromatography - Wikipedia

    en.wikipedia.org/wiki/Column_chromatography

    A chemist in the 1950s using column chromatography. The Erlenmeyer receptacles are on the floor. Column chromatography in chemistry is a chromatography method used to isolate a single chemical compound from a mixture. Chromatography is able to separate substances based on differential absorption of compounds to the adsorbent; compounds move ...

  8. Theoretical plate - Wikipedia

    en.wikipedia.org/wiki/Theoretical_plate

    In industrial continuous fractionating columns, N t is determined by starting at either the top or bottom of the column and calculating material balances, heat balances and equilibrium flash vaporizations for each of the succession of equilibrium stages until the desired end product composition is achieved.

  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.
