I would like to ask anyone what %C they usually get for the NIST 1547
peach leaves.  From the original round robin that Rick and his
colleagues so kindly organized the %C averaged out to 45.5%.  However,
this would seem to be too low, and using a normal C/N analyzer set up
for % we have come up with 47.2%.  Does anyone else have a %C on this
material?
