What is Composition Analysis?

Composition analysis involves determining the elemental and structural makeup of a material. This process is crucial for understanding the material's properties, performance, and potential applications. It encompasses a range of techniques designed to analyze different aspects of a material's composition, from its elemental constituents to its molecular structure.

Techniques Used in Composition Analysis

At Universallab, we employ a variety of advanced techniques to perform composition analysis. Each technique is selected based on the specific requirements of the sample and the type of information needed.

Energy Dispersive Spectroscopy (EDS): Used in conjunction with electron microscopy to identify elemental composition by detecting X-rays emitted from a sample during electron beam interaction3.

Electron Energy Loss Spectroscopy (EELS): Measures the energy lost by electrons as they pass through a sample, providing information about its electronic structure and composition3.

Raman Spectroscopy: Provides molecular information by measuring vibrational modes in a sample3.

Ultraviolet-Visible Spectroscopy (UV-Vis): Analyzes compounds based on their absorption of UV and visible light3.

X-ray Photoelectron Spectroscopy (XPS): Determines elemental composition and chemical states by measuring kinetic energy of electrons ejected from a sample surface3.

Secondary Ion Mass Spectrometry (SIMS): Analyzes surface composition by sputtering with an ion beam and measuring ejected secondary ions3.
