  2. Magnetic separation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_separation

    A large diversity of mechanical means are used to separate magnetic materials. [2] During magnetic separation, magnets are situated inside two separator drums which bear liquids. Due to the magnets, magnetic particles are being drifted by the movement of the drums. This can create a magnetic concentrate (e.g. an ore concentrate). [2]

  3. List of purification methods in chemistry - Wikipedia

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

    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) versus adsorbent (stationary phase) the components in the original mixture pass through the column in the moving phase at different rates, which ...

  4. Solid-phase reversible immobilization - Wikipedia

    en.wikipedia.org/wiki/Solid-phase_reversible...

    The beads are removed from the magnetic field and resuspended in water or an elution buffer, which releases the nucleic acids from the beads. The mixture is once again placed in a magnetic field, separating the beads from the solution. The solution, which now contains the purified nucleic acids, is removed and used for downstream applications.

  5. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.

  6. Immunomagnetic separation - Wikipedia

    en.wikipedia.org/wiki/Immunomagnetic_separation

    A mixture of cell population will be put into a magnetic field where cells then are attached to super paramagnetic beads, specific example are Dynabeads (4.5-μm), will remain once excess substrate is removed binding to targeted antigen. Dynabeads consists of iron-containing cores, which is covered by a thin layer of a polymer shell allowing ...

  7. Fractionation - Wikipedia

    en.wikipedia.org/wiki/Fractionation

    Fractionation makes it possible to isolate more than two components in a mixture in a single run. This property sets it apart from other separation techniques. Fractionation is widely employed in many branches of science and technology. Mixtures of liquids and gasses are separated by fractional distillation by difference

  8. Boom method - Wikipedia

    en.wikipedia.org/wiki/Boom_method

    magnetic field source driving device for driving the magnetic field source to apply or remove a magnetic field to or from the separation region from outside the liquid passage. When the magnet is brought close to the pipette tip, a magnetic field is applied; when retracted away from the pipette tip, that magnetic field is removed.

  9. Ferrofluid - Wikipedia

    en.wikipedia.org/wiki/Ferrofluid

    Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields. The magnetic attraction of tiny nanoparticles is weak enough that the surfactant's Van der Waals force is sufficient to prevent magnetic clumping or agglomeration.
