overview:

Pre-treatment of ammonium.It is a kind of weak cation exchange, mixed type, water and infiltrating polymer adsorbent, stable in the range of ph 0 ~ 14.
WCX has all the advantages of an HLB.Using WCX's stable and high selective solid-phase extraction method, it can monitor, confirm and quantify the strong alkaline compounds such as quaternary ammonium in various sample matrix.
