  1. SiliaBond® Amine nec

    SiliaBond® Amine nec

    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® TBA Chloride

    SiliaBond® TBA Chloride

    SiliaBond® TBA Chloride (Si-TBACl) may be used in the same way as SiliaBond TMA Chloride. Si-TBACl is more sterically indered, which offers a different selectivity than other anion exchangers.

  3. SiliaBond® TMA Chloride nec (SAX)

    SiliaBond® TMA Chloride nec (SAX)

    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.

  4. SiliaBond® TMA Acetate nec

    SiliaBond® TMA Acetate nec

    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.

  5. SiliaBond® TMA Chloride (SAX)

    SiliaBond® TMA Chloride (SAX)

    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® Diethylamine

    SiliaBond® Diethylamine

    SiliaBond® Diethylamine (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. Silica bound ammonium salt by-products are easily separated by filtration. This diethylamine immobilized on silica gel can be used for the same applications as SiliaBond Dimethylamine. It is a very common supported tertiary amine.

  7. SiliaBond® Amine

    SiliaBond® Amine

    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.

  8. SiliaPrep™ SPE Cartridges Amine (WAX)

    SiliaPrep™ SPE Cartridges Amine (WAX)

    SiliaPrep Amine is a weak anion exchanger sorbent used in replacement of SAX for strong anions to avoid irreversible retention. Can also be employed as a metal scavenger and in normal phase conditions.

  9. SiliaPrep™ SPE Cartridges Amine nec (WAX)

    SiliaPrep™ SPE Cartridges Amine nec (WAX)

    SiliaPrep Amine nec is a weak anion exchanger sorbent used in replacement of SAX for strong anions to avoid irreversible retention. Can also be employed as a metal scavenger and norman phase conditions.

  10. SiliaPrep™ SPE Cartridges Diethylamine (WAX-2)

    SiliaPrep™ SPE Cartridges Diethylamine (WAX-2)

    SiliaPrep Diethylamine (WAX-2) is a weak anion exchanger that can be used in replacement of SAX and SAX-2 for strong anions to avoid irreversible retention. This phase presents a slightly lower capacity and a moderate non polar character due to the alkyl chain on the amino function. Moreover, it can be employed as metal scavenger and in normal phase conditions.

  11. SiliaPrep™ SPE Cartridges TMA Chloride nec (SAX)

    SiliaPrep™ SPE Cartridges TMA Chloride nec (SAX)

    SiliaPrep TMA Chloride (SAX) is a strong anion exchanger sorbent positively charged under all conditions used to extract acid molecules (pKa 3-5).

  12. SiliaPrep™ SPE Cartridges TMA Acetate nec

    SiliaPrep™ SPE Cartridges TMA Acetate nec

    SiliaPrep TMA Acetate (SAX-2) is a strong anion exchanger sorbent with a low selectivity acetate counter ion already in place. This sorbent retains more favorably acidic compounds with pKas <5, such as carboxylic acid.
