Hello Everyone,

I have a hopefully quick question about running enriched d15N
samples.  I've done this before and know about the possibilities of
contaminating the various columns in the EA.  However, before the
samples were only somewhat enriched (100 permil).  When testing a
recent batch of samples to see just how enriched they where one
sample gave a value of 4000!  I've already told the researcher that
he must weigh his samples elsewhere.  I don't want this stuff loose
in the lab.  Now my question.  Is there any danger to the mass
spectrometer (i.e., the collectors) if we run such obscenely enriched
samples?

Any help would be greatly appreciated.

Jennifer
