  2. Adsorption - Wikipedia

    en.wikipedia.org/wiki/Adsorption

    However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms and therefore can attract adsorbates. The exact nature of the bonding depends on the details of the species involved, but the adsorption process is generally classified as physisorption (characteristic of weak van der Waals forces ) or ...

  3. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed ...

  4. Expanded bed adsorption - Wikipedia

    en.wikipedia.org/wiki/Expanded_bed_adsorption

    The major limitations associated with EBA technology is biomass interactions and aggregations onto adsorbent during processing. [2] Where classical column chromatography uses a solid phase made by a packed bed, EBA uses particles in a fluidized state, ideally expanded by a factor of 2. Expanded bed adsorption is, however, different from ...

  6. Column chromatography - Wikipedia

    en.wikipedia.org/wiki/Column_chromatography

    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 through the column at different rates, allowing them to be separated into fractions.

    The volatile compounds are drawn along a heated line onto a 'trap'. The trap is a column of adsorbent material at ambient temperature that holds the compounds by returning them to the liquid phase. The trap is then heated and the sample compounds are introduced to the GC–MS column via a volatiles interface, which is a split inlet system.

  8. Absorption (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Absorption_(chemistry)

    The process of gas or liquid which penetrate into the body of adsorbent is commonly known as absorption. IUPAC definition absorption : 1) The process of one material (absorbate) being retained by another (absorbent); this may be the physical solution of a gas, liquid, or solid in a liquid, attachment of molecules of a gas, vapour, liquid, or ...

  9. Elution - Wikipedia

    en.wikipedia.org/wiki/Elution

    Elution then is the process of removing analytes from the adsorbent by running a solvent, called an "eluent", past the adsorbent–analyte complex. As the solvent molecules "elute", or travel down through the chromatography column, they can either pass by the adsorbent–analyte complex or displace the analyte by binding to the adsorbent in its ...
