The new Near-Ambient Pressure X-ray Photoelectron Spectroscopy (NAP-XPS) at iNano offers an advanced platform for detailed surface chemical analysis of materials under near-realistic environmental pressures (20 mbar). Equipped with dual Aluminium and Chromium X-ray sources for versatile spectral capability (analysis depth ~10–30 nm), it features a directly coupled glove box for preparing air-sensitive samples and a vacuum suitcase for contamination-free sample transfer.
NAP-XPS is a powerful technique for probing the dynamic surface chemistry of materials critical to energy storage, catalysis, and polymer science. It provides in situ insights into the chemical states and interfacial reactions of battery electrodes, catalytic surfaces, and polymer interfaces under operating or ambient conditions, enabling a molecular-level understanding essential for advancing material performance and durability.
