EDS analysis, or energy-dispersive spectroscopy, utilizes an electron microscope to produce a focused scanning electron beam that excites the sample material’s atoms, causing characteristic x-ray spectrums to be emitted. Every element has a unique atomic structure that allows a distinctive electromagnetic emission spectrum to be observed. Our technicians can analyze these emission spectrums to quantify and identify unknown materials. EDS is useful in determining the chemical and physical properties of a material. Applied Technical Services has the capabilities to conduct EDS on materials such as metal chips, metal platings, contaminant particles, and corrosion products. Our team utilizes EDS analysis to assist clients with failure analysis, material identification, research studies, and various applications. EDS analysis generally accompanies SEM (scanning electron microscopy) to provide comprehensive knowledge of a material’s characteristics. ATS commonly performs SEM-EDS analysis for the following materials:
