In my paper files I have results from a round robin of NIST 1547 from
the Environmental Isotope Lab at the University of Waterloo dated
1999\8\12 and one from Jeff Owen from 1998. I don't know that these
were ever published. I am not sure if I should send out the data to the
list without the author's permission. You can contact me off list
"[log in to unmask]" for the data or contact the original authors.
Sorry I cannot be more specific.

If this has already been done, might you kindly respond with the reference or some such info. If not and I receive enough submissions, I shall post the results on our lab page and make the list aware. You can choose anonymity if you like. I am not interested in comparing labs. I am interested in the material itself and perhaps informal consensus values. If you are interested, please provide me with:
