  2. Supercritical fluid chromatography - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid...

    Supercritical fluid chromatography (SFC) [1] is a form of normal phase chromatography that uses a supercritical fluid such as carbon dioxide as the mobile phase. [2] [3] It is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules and can also be used for the separation of chiral compounds.

  3. Supercritical fluid - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid

    Supercritical fluid chromatography (SFC) can be used on an analytical scale, where it combines many of the advantages of high performance liquid chromatography (HPLC) and gas chromatography (GC). It can be used with non-volatile and thermally labile analytes (unlike GC) and can be used with the universal flame ionization detector (unlike HPLC ...

  4. Chiral analysis - Wikipedia

    en.wikipedia.org/wiki/Chiral_analysis

    Chiral chromatographic assay is the first step in any study pertaining to enantioselective synthesis or separation. This includes the use of techniques viz. gas chromatography (GC), high performance liquid chromatography (HPLC), chiral supercritical fluid chromatography (SFC), capillary electrophoresis (CE) [35] and thin-layer chromatography (TLC).

  5. Supercritical fluid extraction - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid_extraction

    The supercritical solvent is passed into a vessel at lower pressure than the extraction vessel. The density, and hence dissolving power, of supercritical fluids varies sharply with pressure, and hence the solubility in the lower density CO 2 is much lower, and the material precipitates for collection. It is possible to fractionate the dissolved ...

  7. Chromatography detector - Wikipedia

    en.wikipedia.org/wiki/Chromatography_detector

    A chromatography detector is a device that detects and quantifies separated compounds as they elute from the chromatographic column.These detectors are integral to various chromatographic techniques, such as gas chromatography, [1] liquid chromatography, and high-performance liquid chromatography, [2] and supercritical fluid chromatography [3] among others.

  8. Supercritical carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Supercritical_carbon_dioxide

    More specifically, it behaves as a supercritical fluid above its critical temperature (304.128 K, 30.9780 °C, 87.7604 °F) [1] and critical pressure (7.3773 MPa, 72.808 atm, 1,070.0 psi, 73.773 bar), [1] expanding to fill its container like a gas but with a density like that of a liquid. Supercritical CO

  9. Chiral column chromatography - Wikipedia

    en.wikipedia.org/wiki/Chiral_column_chromatography

    For example, one class of the most commonly used chiral stationary phases both in liquid chromatography and supercritical fluid chromatography is based on oligosaccharides [4] such as Amylose Cellulose or Cyclodextrin (in particular with β-cyclodextrin, a seven sugar ring molecule) immobilized on silica gel.
