The standard method of soft X‐ray beamline calibration at the N K ‐edge uses the ν = 0 peak transition of gas‐phase N 2 . Interstitial N 2 gas trapped or formed within widely available solid‐state ammonium‐ and amine‐containing salts can be used for this purpose, bypassing gas‐phase measurements. Evidence from non‐nitrogen‐containing compounds (KH 2 PO 4 ) and from He‐purged ammonium salts suggest that production of N 2 gas is through beam‐induced decomposition. Compounds with nitrate or nitrite as anions produce coincident features and are not suitable for this calibration method.
