Doug, Here is Canada there is an associated called the Canadian Association of Environmental Analytical Laboratories that labs join and then CAEAL gives labs each year known, blind samples that they must test and get respectable results on. There must be an equivalent association in the US. Rudy has already pointed out that there are many poor labs, so you need some measure of telling who is good, if you are going to use a lab for which you do not have a solid endorsement. Also, even if a lab is good, if they are not used to testing the type of sample you have in mind, the results may still be questionable. Good luck in your hunt. Bev RIM PS I know you have a hard time sending stuff away to a foreign country, but if you could send it to the Great White North, we can recommend some good labs. Monday is Victoria Day (a holiday) Long Live the Queen! (and partially because that gives us a holiday. I hope this does not upset any of our fervent Quebecois. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Douglas O. Pauls Sent: Friday, May 16, 2008 12:10 PM To: [log in to unmask] Subject: [TN] GCMS Good morning all, I find myself in need of a test lab that does gas chromatography mass spectroscopy (GCMS). Are there any labs that you would recommend? Sadly, I don't have this capability in house.
