Nuceosil SAX chemistry

Hi,

I have read in a paper that Nucleosil SAX silica contains a benzene ring in the chain linking the anion-exchanger to the silica. This makes it slightly different to other SAX materials which use a propyl group. Can anyone confirm that this is the case?

Thanks for your help.

This is true, Nucleosil SA uses benzenesulfonic acid ligand and SB the corresponding quarternary amine.
