Using Scanning Electron Microscopy/X-Ray Spectrometry in Forensic Paint Examinations

ASTM E2809
 
The SEM can be used to define and compare the layer structure of multilayered samples, the structure of individual layers, the bulk elemental composition of individual layers, and the elemental composition of individual particulate components within paints and coatings. The test methods described may have some limitations. They include the inability to detect elements in trace concentrations, the need for a conductive coating of the sample, the inability to remove a sample from most embedding materials after analysis, and the discoloration of materials by irradiation.
WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM E2809 for Using Scanning Electron Microscopy/X-Ray Spectrometry in Forensic Paint Examinations. Contact us to learn more.
