Urumu:

The University of Waterloo has been compiling the results of a ring test of
the carbon and nitrogen elemental and isotopic compositions of several NIST
standards.  Included among these standards are NIST 2682a, a sub-bituminous
coal, and NIST 2685a, a bituminous coal.

The preliminary results of this test have been discussed at recent Canadian
CF-IRMS meetings in Waterloo and Ottawa.  Contact Bill Mark at
