Peter,
ISOTEC Inc. provides 15N-labelled N2O (99 5 atm) in pressurezed bottles. It
is rather expensive though.

Subject: [ISOGEOCHEM] 15N in N2O analysis
Hi,
Can anyone tell me if it's possible to purchase N2O-reference gas
with various 15N abundances? For the moment we use N2O that is
made by chemical tranfsormation from NO3-. The procedure to
transform NO3- in N2O is time-absorbing and it involves the use of
Cadmium.
Is there another way to acquire N2O reference gas?
Thank you very much.
