ProElut™ NH₂

ProElut™ NH₂ has both polar and weak anion exchange interactions. It can effectively absorb compounds with a polar functional group (-OH, -NH₂,-SH, etc.) by hydrogen bonding from non-polar solvents such as hexane.
In addition, it has weaker anion exchange property than SAX (a quaternary amine sorbent that is always charged) and is therefore an excellent choice for retention of very strong anions that are always irreversibly adsorbed on a SAX sorbent, such as sulfonic acid.
