I should have thought about the spec idea before !. The MDSD for 
cloroquine was not that informative in that it mentions activated 
charcoal but no real binding info. Maybe the Merck one will be better. 
Generally we use activated charcoal "teabags" for removal of EtBr 
which gets around the dust problem.
