Try Tosohaas (www.tosohaas.com). They produce a similar chelating resin
called Toyopearl. I have previously tried to prepare the 8-hydroxy resin
in my lab, with poor results.

Subject: silica-immobilzed 8-hydroxyquinoline for seawater analyses?
There has been discussion on this list in the past re: the usage of
8-hydroxyquinoline immobilised on silica gel to separate analytes from the
seawater matrix. This reagent is typically made in-house using Hill's
procedure (J.M. Hill, Journal of Chromatography, 1973 v. 76, p.455),
however it appears not to be a straightforward excersise to prepare this
reagent consistently. My question to the Plasmachemer's is -do any of you
know of a commerical source for this material?
Thanks in advance,
