SEM-EDS Analysis Identifies Material Condition 


SEM (scanning electron microscopy) analysis consists of concentrating a focused beam of high-energy electrons, which generates a number of signals at the surface of solid specimens. These signals, which are gleaned from electron-sample interactions, relay important information about the sample, such as texture, microstructure, the processes performed on the material during manufacture, and whether the material meets the needed specifications to ensure optimal durability in the intended application.       

SEM is relatively simple to carry out with proper training, and corresponding software can greatly enhance ease of use. Plus, the microscopes used in this process are able to generate data in a sophisticated digital form. SEM is also very fast; some analyses can be completed in under 15 minutes. 

The EDS component of the system is applied in conjunction with SEM analysis to determine elements in or on the surface of the sample for qualitative information. Utilizing the EDS feature measures the elemental composition in or on the surface, and identifies foreign substances.
