Title: osmium tetraoxide
Post by: thedivine on April 04, 2005, 12:34:42 PM
Hi,
I'm looking for to choose a selective staining for polystyrene against polyethyleneoxyde. Before, I've tried ruthenium tetraoxide, but unsuccesfully.
I've plenty of hopes with osmium tetraoxide, but I don't know precisely its staining mecanism: do you think that polyethyleneoxide will be preserved from OsO4? Have you some tips about it?
Thank you.
