nice idea but no go all their stuff is on a database an if the compound isn't in the database they don't recognize it. Also, they always start with immunoassay. No skills there for handling unknowns. MS analyses are an art requiring constant practice. I'd like a good place to check things too. Try to get a surplus NMR. Shulgin did once offer that service in SF. Laws were passed to shut it down. Can't have experimenters getting any help with QA/QC. <CHARLIEFROMWASHINGTON@YAHOO.COM> wrote in message news:1167373438.789987.290550@73g2000cwn.googlegroups.com... > ya just put a speck of the substance in a cup of piss and sent it > to a drug testing lab >
