Just read that thread - interesting stuff and fun to watch everyone come together for the test - this raises a question in my mind however:
My dad is about to retire as a manager of a large laboratory here in Houston. They have almost every kind of lab equipment you could name. I know GC Mass Spec. would be no problem as they have a few machines, but I'm not sure about the NMR, I'd have to ask. Is there a chemist here who could tell me how much it would cost in materials to run this test. Labor would be no problem as I know a few guys up there who are qualified to run the GC. I know they can test down to the ppb (parts per billion) level for some things... This may be prohibitively expensive. I can get the results for sure, and I know there's some folks on here that could read them. Just thinking out loud. My background is in English and computers, so all I know about lab testing is what I've heard over the dinner table growing up.
