I am just setting up to begin H/D analysis, and have been told that regular
bulk tank H2 is always so depleted that it is useless to use as a reference
gas.  What do other users do for a H2 reference gas here in N. America?  Is
there a supplier of a bulk gas in a reasonable range?  I already have a
small tank of calibrated H2 but it is much too expensive to use as a day to
day reference gas.

Thanks in advance,

Paul D. Brooks.
