Materials Characterization: ESCA Analysis

Materials Analyst Performs ESCA Test

ESCA analysis, also known as Electron Spectroscopy for Chemical Analysis or X-Ray Photoelectron Spectroscopy (XPS), is a surface analysis technique that provides elemental and binding energy information about a material's surfaces and interfaces.

Innovatech Labs provides prompt service on all ESCA analysis samples. In fact, most samples can be analyzed in five or fewer business days. Contact us to submit a sample.

ESCA is a good materials analysis technique for:

  • Evaluating the passivation of stainless steels and the oxidation of chromium and iron
  • Studying the surface chemistry of polymers, glasses and other insulators.
  • Resolving issues related to metal interdiffusion, resin-to-metal adhesion and oxidation.

Samples for ESCA (XPS) can be conductive or non-conductive materials. Sample size should be around 0.5 square inches with a maximum thickness of about 0.25 inches. The spot size for the system used by Innovatech Labs is approximately 1mm.

This surface analysis technique utilizes an x-ray beam to excite the molecules on the surface of a solid material, resulting in the emission of photoelectrons. An energy analysis of these photoelectrons provides both elemental and chemical bonding information about a sample surface.

ESCA analysis can detect all elements from lithium to uranium with detection limits of ca. 0.1 atomic percent.
