Materials Characterization & Surface Analysis

Materials can be characterized by many different analytical approaches. The Materials Characterization division of Evans Analytical Group® (EAG), uses about 30 different methods to provide answers to our customers. Generally the techniques used for a given problem are selected based on the information needed and the form the sample is in. Most of the common techniques are for the analysis of solid samples, although liquid and gas sampling is possible in some cases. Two common potential analytical are as follows:

  • The material of interest has already been identified but further information about specific properties is required, e.g. interface sharpness, the depth distribution of a particular element, morphology, crystal structure, thickness, stress, and quality (or many other characteristics).
  • The material of interest has not been identified and is not well characterized. Information is required about the identity and composition of the material.
