Alumicel™ A

Purifies via separation of compounds by relative polarity and charge.

  • Adsorption Selectivity: 6/10
    [ability to target specific compounds]
  • Adsorption Rate: 9/10
    [speed of compound separation/removal]
  • Fluid Flow Rate: 6/10
    [speed of solution through media]
  • Binding Affinity: 5/10
    [strength of adhesion to compounds]
  • Purpose

    Alumicels are polar stationary phases for normal phase column chromatography. These high purity, acid/base-activated alumina products are also used in polishing filter beds, decolorizations, and as adsorbents for strong polar impurities, including sequestering H+ & OH- ions. Alumicels can also improve flow rates through clays.

  • Composition

    Alumicel™ A is a fine grain (50–150 μm), highly porous, pure aluminum oxide powders that have been thermally and chemically activated for specific pH and polar surface functionality. Alumicel™ A is acidic (pH 4.0–5.0). These high hardness, insoluble particles offer maximum stability and bed support strength.

  • Particle Size & pH

    Alumicel™ A has a particle size of 50–150 μm and a acidic pH of 4.0-5.0.
