We present an in-situ, depth-resolved and non-destructive approach to assess the chemical composition of titanium nitride (TiN) thin films during synthesis and controlled oxidation. Ion beam assisted deposition was used to deposit a TiN sample of approximately 120 nm thickness. The chemical composition was characterized in the deposition environment using non-destructive Rutherford/Elastic Backscattering
