Beyond acceptable limits: intrinsic contamination in commercial 15N2 impedes reliable N2 reduction experiments

Abstract

The validity of N2 reduction experiments relies on control experiments with isotopically labeled 15N2. Here we discovered significant 15NH3 contamination (73 ppm) in commercial 15N2 and also observed the prescence of oxidized 15N in amounts comparable to the typical reported ammonia yields.
