The NAP-XPS facility at iNANO, Aarhus University, provides advanced surface chemical analysis under near-realistic environmental conditions. It is designed for researchers who want to investigate the chemistry of functional materials, interfaces, and reactive surfaces in situ, operando, or after controlled sample treatment.
Operating at pressures up to 20 mbar, the system is equipped with dual Aluminium and Chromium X-ray sources for versatile spectral capability and an analysis depth of approximately 10–30 nm. The platform also includes a directly coupled glove box for preparing air-sensitive samples and a vacuum suitcase for contamination-free sample transfer.
NAP-XPS makes it possible to follow chemical changes at surfaces and interfaces under conditions that are much closer to real operation than conventional ultra-high-vacuum XPS. This enables molecular-level insight into reaction intermediates, interfacial chemistry, degradation processes, and surface composition in complex material systems.
