In this blog, we will explore what XPS testing is, its applications, benefits, industries served, and how to choose the best XPS testing lab in India.

What is XPS Testing?

X-ray Photoelectron Spectroscopy (XPS), also known as Electron Spectroscopy for Chemical Analysis (ESCA), is a surface-sensitive analytical technique used to determine:

• Elemental composition

• Chemical states of elements

• Surface contamination

• Oxidation states

• Thin film characterization

• Coating analysis

The technique works by irradiating a material surface with X-rays and measuring the kinetic energy of emitted electrons. Since XPS analyzes only the top few nanometers of a surface, it provides highly accurate surface chemistry information.
