X-Ray Photoelectron Spectroscopy (XPS)
X-Ray Photoelectron Spectroscopy (XPS) also known as Electron Spectroscopy for Chemical Analysis (ESCA) is a highly surface sensitive quantitative chemical analysis technique that can be used to solve a wide range of materials problems. This facility with UV upgrade enables surface analysis, providing elemental composition as well as the chemical and electronic state of the top 10 nm of a material. With depth profiling, XPS analysis extends to compositional insight of layers.
