SiliaBond®- Bases
In order to simplify the use and the removal of bases and their salts from reaction mixtures, SiliCycle has developed a range of silica bound SiliaBond bases :
-
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 norman phase conditions.
-
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.
-
SiliaPrep™ SPE Cartridges Piperazine (SPE-R60030B)
SiliaPrep Piperazine is a weak anion exchanger that can be used in replacement of SAX and SAX-2 for strong anions to avoid irreversible retention. By using this phase, elution can be done at a lower pH (around pH 8-9) comparatively to the SiliaPrep Amine.
-
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.
-
SiliaPrep™ SPE Cartridges Carbonate
SiliaPrep Carbonate (or Si-CO3) is the silica bound equivalent of tetramethyl ammonium carbonate. It can be used as a general base to quench a reaction, to free base amines in their ammonium salt form and to scavenge acids, boronic acids and acidic phenols, including HOBt, which is widely used in amide coupling reactions.
-
SiliaPrep™ SPE Cartridges Diamine
SiliaPrep diamine can be used in replacement of SAX for strong anions to be irreversible retention. Can also be employed as metal scavenger and in normal-phase conditions.
-
SiliaPrep™ SPE Cartridges Diamine nec
SiliaPrep diamine can be used in replacement of SAX for strong anions to be irreversible retention. Can also be employed as metal scavenger and in normal-phase conditions.
-
SiliaPrep™ SPE Cartridges Triamine
SiliaPrep Metal Scavengers will lower the residual metal concentration of various metal complexes to single digit ppm.
