Hello Everyone,

I need to measure the d13C and d15N of organic matter in volcanic
lake sediments.  The problem is that the sulphur in these samples
"kills" the combustion column in the EA after only 250 samples.   We
have resorted to running the samples only when a column nears the end
of its life.  I was wondering if anyone can suggest a better solution
and provide general advice on how to handle S-rich samples.

Yours truly,
Jennifer
