  1. SiliaBond Amine (WAX) (R52030B)

    SiliaBond Amine (WAX) (R52030B)

    SiliaBond Amine (Si-NH2) is an effective scavenger of acid chlorides, sulfonyl chlorides, isocyanates and other electrophiles. Si-NH2 has been shown to be effective metal scavenger and catalyst for Knoevenagel reactions. SiliaBond Amine is also used in chromatography as normal phase sorbent.
  2. SiliaBond Amine (WAX) nec (R52130B)

    SiliaBond Amine (WAX) nec (R52130B)

    SiliaBond Amine (Si-NH2) is an effective scavenger of acid chlorides, sulfonyl chlorides, isocyanates and other electrophiles. Si-NH2 has been shown to be effective metal scavenger and catalyst for Knoevenagel reactions. SiliaBond Amine is also used in chromatography as normal phase sorbent.
  3. SiliaBond TMA Acetate (SAX-2) nec (R66430B)

    SiliaBond TMA Acetate (SAX-2) nec (R66430B)

    Strong anion exchangers (SAX) have been widely used in both chromatography and ion exchange SPE to selectively bind acidic drugs and/or analytes. In particular, weakly acidic compounds can be effectively extracted as those types of sorbents retain a permanent positive charge across the pH range. Most commercially available silica-based SAX sorbents are produced with a high selectivity chloride counter ion which reduced retention of acidic drugs when compared with lower selectivity counter ions such as acetate.
  4. SiliaBond TMA Chloride (SAX)

    SiliaBond TMA Chloride (SAX) (R66630B)

    SiliaBond TMA Chloride (SiliaBond SAX, Si-TMACl) is mainly used as strong anion exchanger (SAX) in ion chromatography and ion exchange SPE. The function bears a positive charge across the whole pH range as well as in organic solvents. It is especially used for the “Catch and Release” purification of weak acids.
  5. SiliaBond TMA Chloride (SAX) nec (R66530B)

    SiliaBond TMA Chloride (SAX) nec (R66530B)

    SiliaBond TMA Chloride (SiliaBond SAX, Si-TMACl) is mainly used as strong anion exchanger (SAX) in ion chromatography and ion exchange SPE. The function bears a positive charge across the whole pH range as well as in organic solvents.

  6. SiliaBond Triethylamine (TEA) (R76530B)

    SiliaBond Triethylamine (TEA) (R76530B)

    SiliaBond Triethylamine (SiliaBond WAX-2) is a silica bound tertiary amine base and can be used in most applications requiring a tertiary amine, particularly as a HCl sponge. SiliaBond Triethylamine is also used as weak anion exchanger (WAX) in SPE.
