HI Steve--

We'll part with some if you'd like.

We tend to run both sulfate and sulfide standards to make sure we don't 
have any thing funky going on with the oxygen.  We only do S 
periodically--and we do it on a Costech using the single reactor set up 
(usually pre-packed).  You may want to check with people who run it 
regularly via the EA, and there have been some nice tidbits earlier on 
the listserve.  Gilles helped us out with problems we were having with 
organic samples.

take care

gerry
