The recent posts by William Mark, and Paul Brooks have got me enthusiastic 
again about pooling resources between labs to address standardization for 
CNOS and H in particular.
I would really be interested to see a compilation of all the working 
standards that are being used in the labs, along with what primary isotope 
reference they were calibrated against.  Perhaps we should devote a 
special session to the CF-IRMS workshop this year to work up a spreadsheet 
we could post, and compile as many contributions as we can, making it 
available to all.  A lot of work, but something that could be very useful.
