Normal Phases

Normal phase chromatography is used to separate polar compounds through polar interactions with the support. The interactions take place on the highly polar silanols of the silica gel surface, but there are also moderately polar interactions with the hydrogen bonds on Amino or Diol functions.

  1. SiliaSep Flash Cartridges, Silica, 40 - 63 µm, 60 Å (FLH-R10030B)

    SiliaSep Flash Cartridges, Silica, 40 - 63 µm, 60 Å (FLH-R10030B)

    Most popular sorbent for day-to-day use for the purification of non-ionic polar organic compounds.
  2. SiliaSep Flash Cartridges, HP Silica, 15 - 40 µm, 60 Å (FLH-R10017B)

    SiliaSep Flash Cartridges, HP Silica, 15 - 40 µm, 60 Å (FLH-R10017B)

    High Performance sorbent for difficult separations (isomers). Higher loading capacity. Faster flow rate. Less solvent used.
  3. SiliaSep Flash Cartridges, Amine (WAX), 40 - 63 µm, 60 Å (FLH-R52030B)

    SiliaSep Flash Cartridges, Amine (WAX), 40 - 63 µm, 60 Å (FLH-R52030B)

    A weak anion exchanger with a pKa of 9.8. At pH 7.8 or below, the functional groups are positively charged. It facilitates the rapid release of very strong anions such as sulfonic acids that may be too strongly retained on SAX.
  4. SiliaSep Flash Cartridges, Cyano (CN), 40 - 63 µm, 60 Å (FLH-R38030B)

    SiliaSep Flash Cartridges, Cyano (CN), 40 - 63 µm, 60 Å (FLH-R38030B)

    Versatile sorbent that can be used either as normal or reversed-phase. Indicated for products with intermediate to extreme polarity. The slightly hydrophobic nature of the cyano group offers alternative selectivity.
  5. SiliaSep Flash Cartridges, Diol nec, 40 - 63 µm, 60 Å (FLH-R35030B)

    SiliaSep Flash Cartridges, Diol nec, 40 - 63 µm, 60 Å (FLH-R35030B)

    Good alternative for difficult separation of low to medium polarity samples. Useful for mono and polysaccharides separation. Can be used in HILIC mode.
  6. SiliaSep Flash Cartridges, Neutral Alumina, 50 - 200 µm, 60 Å (FLH-AUT-0054)

    SiliaSep Flash Cartridges, Neutral Alumina, 50 - 200 µm, 60 Å (FLH-AUT-0054)

    Good retention of aromatic compounds, aliphatic amines and compounds containing electronegative functions.
  7. SiliaSep Flash Cartridges, Basic Alumina, 50 - 200 µm, 60 Å (FLH-AUT-0055)

    SiliaSep Flash Cartridges, Basic Alumina, 50 - 200 µm, 60 Å (FLH-AUT-0055)

    Good retention of aromatic compounds, aliphatic amines and compounds containing electronegative functions.
  8. SiliaSep Flash Cartridges, Acidic Alumina, 50 - 200 µm, 60 Å (FLH-AUT-0053)

    SiliaSep Flash Cartridges, Acidic Alumina, 50 - 200 µm, 60 Å (FLH-AUT-0053)

    Good retention of aromatic compounds, aliphatic amines and compounds containing electronegative functions.
  9. SiliaSep Flash Cartridges, Silver Nitrate (AgNO3), 40 - 63 µm, 60 Å (FLH-R23530B)

    SiliaSep Flash Cartridges, Silver Nitrate (AgNO3), 40 - 63 µm, 60 Å (FLH-R23530B)

    Mainly used for the separation of cis / trans isomers of unsaturated compounds such as alkenes, lipids, steroids and terpenes.
