An X‐ray photoelectron spectroscopy (XPS) instrument is utilized for sputter depth profiling of thin films. Relevant instrumental parameters are the ion gun sputter rate, the contamination level of the sputter ion gun, and the purity of the sputter ion gun gas supply as well as the vacuum quality of the instrument at the sample position. A long‐term recording of these instrumental parameters ensures the reliability of the measured depth profile data.
