  • US Patent for Separation of gases containing SF6 Patent

    Feb 20, 2001 · 12 zeolites were investigated in terms of their suitability as adsorbents for separating SF6/N2 mixtures. An SF6/N2 mixture co ntaining about 1% by volume SF6 was passed over two adsorbers connected in series, which contained a bed of 500 ml of the respective adsorbent. The mixture was passed through until about 10 g SF6 had been passed through.

  • Porous Organic Cages for Sulfur Hexafluoride Separation

    A series of porous organic cages is examined for the selective adsorption of sulfur hexafluoride (SF6) over nitrogen. Despite lacking any metal sites, a porous cage, CC3, shows the highest SF6/N2 selectivity reported for any material at ambient temperature and pressure, which translates to real separations in a gas breakthrough column. The SF6 uptake of these materials is considerably higher

  • GC-MS Background

    Jan 20, 1998 · In general, chromatography is used to separate mixtures of chemicals into individual components. Once isolated, the components can be evaluated individually. In all chromatography, separation occurs when the sample mixture is introduced (injected) into a mobile phase. In liquid chromatography (LC), the mobile phase is a solvent.

  • High-performance liquid chromatography - Wikipedia

    Separation factor (alpha) is a relative comparison on how well two neighboring components of the mixture were separated (i.e., two neighboring bands on a chromatogram). This factor is defined in terms of a ratio of the retention factors of a pair of neighboring chromatogram peaks, and may also be corrected for by the void volume of the column.

  • Fractional distillation - Wikipedia

    Some mixtures form azeotropes, where the mixture boils at a lower temperature than either component. In this example, a mixture of 96% ethanol and 4% water boils at 78.2 °C (172.8 °F); the mixture is more volatile than pure ethanol. For this reason, ethanol cannot be completely purified by direct fractional distillation of ethanol-water mixtures.

  • Fast protein liquid chromatography - Wikipedia

    Fast protein liquid chromatography (FPLC), is a form of liquid chromatography that is often used to analyze or purify mixtures of proteins. As in other forms of chromatography, separation is possible because the different components of a mixture have different affinities for two materials, a moving fluid (the mobile phase) and a porous solid (the stationary phase).
