Hi Anette,
You can get single crystal GaN commercially.  I have some.  Is this trace nitrogen?  In which case the standard doesn't really matter.  So boron nitride would also work...

You might also post your request here:

Dear all,

I have project on nitrogen in various materials in my lab and am trying to find a iron nitride that is not a powder for associated SIMS work (so GaN won't do).

Does anyone know of a source or even have some to share? Willing to pay or otherwise have various other materials to trade.

Thank you!

Best,

Anette
