SiliaBond®- Ion Exchanges
The sorbent required for the purification of a specific substrat will vary according to the structure of the said substrate. Wether it is ionized or neutral and depending on its polarity and solubility, the appropriated chromatographic stationary phase will vary. In order to better fulfill those different needs, SiliCycle offers a wide variety of sorbents including ion exchanger resin. These latest can also be used in “Catch and Release” purification technique (see application notes section for detailed protocol). Please refer to the sorbent selection guide to select the most appropriated phase.
-
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 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 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).
-
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.
-
SiliaPrep™ SPE Cartridges Carboxylic Acid (WCX)
SiliaPrep Carboxilic Acid is a weak cation exchanger sorbent (WCX) used to extract strong basics compounds.
-
SiliaPrep™ SPE Cartridges Carboxylic Acid nec (WCX)
SiliaPrep Carboxilic Acid nec is a weak cation exchanger sorbent (WCX) used to extract strong basics compounds.
-
SiliaPrep™ SPE Cartridges Tosic Acid (SCX)
SiliaPrep Tosic Acid (SCX) is a strong cation exchanger and maintains a negative charge throughtout the pH scale. The most common use is a strong cation exchanger for the amine and basics molecules "catch and release" purification technique in SPE cartridges.
