Is there a material (huge) difference between the cost of certified reference materials (chemicals) and other? And if so: what would you estimate the difference to be (possibly expressed as a percentage)? By "other" I don't mean of the cost of the (possibly questionable) Chinese variety i.e. I'm referring to the registered, regulated. and reputable chemical manufacturers and suppliers that supply certified reference materials (chemicals).
I realize it's possibly a moot point i.e. depending on the reference material (chemical) said manufacturers and suppliers seem to, usually anyway, only supply certified reference materials (chemicals) i.e. there's no lower grade alternates.
