Dear list members, I mailed this privately to the original poster, but then read the response that perhaps more replies should be sent to the list, so here is my $0.02. Please use a big grain of salt with this one: From: USU::MYQ "MYQ Y. Q. LARSON" 5-FEB-1998 12:44:08.52 To: [log in to unmask] CC: MYQ Subj: MS musings Hi, Saw your post about buying an IRMS possibly from Europa. We have a 20/20 Europa analyzer coupled with an ANCA/SL Europa prep unit. We only run N, so I can't really comment too much on your sample requirements, but we can run down to 20 - 10 ug N within the specified precision of the machine, but it takes some tweaking... As far as service/support goes - I haven't had very good experience with them. They seem very unknowledgable when I have a problem and not very enthusiastic about assisting me. I asked for a price quote on a few parts in December and have yet to receive the fax they promised. The first machine we got was a lemon and took about 4 months of complaining/trying their solutions before they replaced it. Generally, the other Europa users I have talked to agree that they have poor support. However, other Europa users have been more than kind and very helpful. The machine is VERY easy to use (I have a degree in Liberal Arts and Sciences, NOT anything related to chemistry!), and is fairly easy to maintain after a breaking in period (of the operator!). In short, I like the machine, but have very small praise for the company/support/service itself. Of course, I have never operated any other MS device, so be sure to take this with a big 10 lb bag of salt.
