X-ray photoelectron spectroscopy (XPS) is a surface-sensitive quantitative spectroscopic technique that measures the very topmost 50–60 atoms, 5–10 nm of any surface.

By showing the energy of electrons emitted from a material, XPS allows for the composition of a material to be determined. Additionally, chemical shifts can be determined using XPS.

Aug 13, 2021 · What is X-Ray Photoelectron Spectroscopy? X-ray photoelectron spectroscopy (XPS) is a surface sensitive, non-destructive technique used routinely to analyze the outermost ~10 nm (~30 …

This first guide outlines steps appropriate for determining whether XPS is capable of obtaining the desired information, identifies issues relevant to planning, conducting and reporting an XPS …

Dec 6, 2025 · Its function is determining the elemental composition and the specific chemical state of atoms within the top few nanometers of a material’s surface. By analyzing the interaction between …

X-ray photoelectron spectroscopy (XPS) is a powerful analytical technique used to examine the surface of materials, providing valuable insights into both elemental and chemical composition.

Book approx. 1 hour session per sample for simple spectroscopy, contact Emily or Craig for more complex work. Bring samples in labelled containers with MSDS if required. For anything polymer-like …

•Kai Siegbahn developed an instrument for analyzing emitted photoelectrons and used it for chemical analysis •The technique was called Electron Spectroscopy for Chemical Analysis (ESCA) •Awarded …

X-ray photoelectron spectroscopy (XPS) is a relatively new surface-analysis technique (originating in the 1980s) that can be used to elucidate a material’s elemental content and respective chemical bonding.

It is a surface analysis technique with a sampling volume that extends from the surface to a depth of approximately 50-100 Å. XPS Spectroscopy can also be used for sputter depth profiling. This is …
