Sorry -- didn't see the link in your post. Will follow it, and archive it and all available references.

But yeah, I've been going through my archives, and found a bunch of stuff I need to transcribe and post, but also stumbled over a "research report" sent me by an ionizer maker 20 years ago. The irony was that that the analysis -- that the VP marketing sent me -- actually showed that his product didn't work!
