John,

You might want to take a look at the web site for the U. Waterloo stable
isotope lab at http://www.science.uwaterloo.ca/~rkhmskrk/
It looks like they'll run dD and d13C analyses for each of H2, CH4, C2H6,
C3H8, and C4H10 within a natural gas mixture.  They also have a price list
on their web site.  I should point out that I've never had any samples run
for me by this lab.

Cheers,
Simon
