Sorbents AG-1/2/4 are a strong anion exchanger with a quaternary amine functional group. Sorbents AG-2 and AG-4 are weaker anion exchangers than AG-1. The number after the X in the name of the sorbent denotes the% of polymer crosslinking. It is possible to supply sorbents with Biotechnology grade certificates - less than 100 microorganisms / gram of sorbent.
