Hi everyone,

We are currently analyse 18O of AgNO3 using high
temperature pyrolysis system (EuroVector EA and
IsoPrime). But the separation of CO and N2 after
pyrolysis is really complete, and thus the 18O data
doesn't look good.  I was wondering if there is a way
to improve their separation. I have tried to adjust
the flow rate but not much improvement.  Any
suggestion will be appreciated.

Thanks in advance,

River He
