Description

A polymerically bonded quartemary amine that remains changed at all ph leveles
Retains negatively charged componends, especially those that clute from weak anion exchange sorbents
Selectivity can be user-modified for increased flexibility
Minimal non-polar interactions.

Matrix	Silica Gel
Function Groups	Quaternary Amine
Endcapped	No
Carbon Loading	7.5%
Material characteristics	Particle Size:40-60 µm Pore Size: 60A Pore Volume: 0.8cm 3/g Surface Area :480m 2/g
Retention Mechanism	Strong anion -exchange selectivity
applications	Extraction of negatively charged sub –stances from water or aqueous solution, especially for the extraction of weak acids such as carboxylic acids, which may not retain effectively on weak anion exchange sorbents
