  • Silica Gel: Passive Control of Relative Humidity

    Example: Conditioning the silica gel to equilibrium moisture content at 50% RH. According to Appendix 2, 27.07% water (EMC % g/g dry weight) is needed in regular silica gel to be in equilibrium at 50% RH. If you start with 1000 g of dry silica gel, introduce water until the weight of the humid sorbent reaches 1270.7g (1000 x 1.2707).

  • Silica Gel Chromatography Method of High Purity Grade

    It is a technique in which the stationary phase is solid adsorbents like silica gel and activated alumina powder and the mobile phase is a liquid. The principle of active compound separation depends on the activity of adsorbents and polarity of the solvent. If the polarity of the solvent is very low and the activity of the adsorbent is strong and high, then result of separation of compound is

  • Column Chromatography

    Silica gel (SiO 2) and alumina (Al 2 O 3) are two adsorbents commonly used by the organic chemist for column chromatography. An example of each of these adsorbents is shown below. These adsorbents are sold in different mesh sizes, as indicated by a number on the bottle label: "silica gel 60" or "silica gel 230-400" are a couple of examples

  • Thin-layer chromatography Wikipedia

    For example, with silica gel, a very polar substance, non-polar mobile phases such as heptane are used. The mobile phase may be a mixture, allowing chemists to fine-tune the bulk properties of the mobile phase. After the experiment, the spots are visualized. Often this can be done simply by projecting ultraviolet light onto the sheet; the sheets are treated with a phosphor, and dark spots

  • Silicon dioxide Wikipedia

    Silicon dioxide, also known as silica, is an oxide of silicon with the stone formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product. Notable
