Introduction to materials characterization instruments

Materials characterization instruments are specialized tools used to analyze and understand the physical, chemical and structural properties of various materials. These instruments provide essential data for research, development and quality control in multiple industries, from construction to electronics and biomedicine.

The term 'other characterization instruments' covers equipment that does not belong to the most common techniques such as spectroscopy or X-ray diffraction. These instruments complement and expand the ability of researchers to evaluate specific characteristics of materials, providing a more complete view of their behaviors and properties.

Atomic force microscopy (AFM)

Atomic force microscopy (AFM) is a technique that allows obtaining three-dimensional images of the surface of a material with nanometric resolution. It works through a very fine probe that interacts with the surface, detecting attractive or repulsive forces between the tip and the material.

Its ability to operate in different environments, including liquids and controlled atmospheres, and without requiring special preparation of the material, makes it a very versatile tool for studying topographical, mechanical and electrical properties at the nanometer scale.

Furthermore, AFM is essential for investigating biological materials, polymers and functionalized surfaces, facilitating the understanding of phenomena such as adhesion, friction and surface elasticity.

Raman spectroscopy

Raman spectroscopy is an optical technique that is based on the inelastic scattering of light to identify the characteristic molecular vibrations of a material. It allows obtaining detailed information about its chemical composition and molecular structure without having to destroy the sample.
