Energy Dispersive X-Ray (EDS Analysis)

MES provides Energy Dispersive X-Ray Analysis (EDS) analysis for elemental composition of materials. EDS is a semi-quantitative x-ray technique used to identify the elemental composition of materials. Applications include material identification, coating analysis, contaminant identification, and corrosion analysis.

EDS systems are attachments to the Scanning Electron Microscope (SEM) where the imaging capability of the microscope identifies the specimen of interest. The data generated by EDX analysis consist of spectra showing peaks corresponding to the elements making up the true composition of the sample being analyzed. Elemental mapping of a sample and image analysis are also possible. The EDS analysis technique is non-destructive and specimens of interest can be examined with little or no sample preparation.
