XPS: Universal X-Ray photoelectron and ion scatering spectroscopy surface analysis system - ThermoFisher ESCALAB 250Xi
Description:

The ThermoFisher ESCALAB 250Xi is an advanced surface analysis tool designed for both qualitative and quantitative investigations of material surfaces. Utilizing X-ray photoelectron spectroscopy (XPS), ion scattering spectroscopy (ISS), and reflection electron energy loss spectroscopy (REELS), this system provides comprehensive insight into surface chemistry and electronic structure. The addition of angle-resolved XPS (ARXPS) allows for depth profiling, while an Ar ion beam enables precise surface cleaning and etching.
