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.
