  2. Silica gel - Wikipedia

    en.wikipedia.org/wiki/Silica_gel

    Thermal regeneration can be applied also to packed silica gel beds without opening them. Thermal regeneration can be conventional heating in an oven at temperature of about 120 °C . [ 8 ] Another option for thermal regeneration is by using microwaves to apply heat more evenly and reduce regeneration time compared to conventional ovens, but ...

  3. Molecular sieve - Wikipedia

    en.wikipedia.org/wiki/Molecular_sieve

    Regeneration temperatures range from 175 °C (350 °F) to 315 °C (600 °F) depending on molecular sieve type. [12] In contrast, silica gel can be regenerated by heating it in a regular oven to 120 °C (250 °F) for two hours. However, some types of silica gel will "pop" when exposed to enough water.

  4. Bioactive glass - Wikipedia

    en.wikipedia.org/wiki/Bioactive_glass

    A silica gel layer forms on the bioactive glass surface. CaP crystallizes, forming a layer of hydroxyapatite on the surface of the bioactive glass. Once the hydroxyapatite layer is formed, the bioactive glass interacts with biological entities, i.e., blood proteins, growth factors and collagen.

    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.

  8. Desiccator - Wikipedia

    en.wikipedia.org/wiki/Desiccator

    The lower compartment of the desiccator contains lumps of silica gel, freshly calcined quicklime, Drierite, molecular sieves, phosphorus pentoxide, (not as effective) anhydrous calcium chloride, or other desiccant to absorb water vapor. The substance needing desiccation is put in the upper compartment, usually on a glazed, perforated ceramic plate.
