Eds testing and elemental mapping laboratories in US? Analysis and Results: The submitted bottle was examined for signs of interior distress, and the water from the bottle was removed and maintained. Some of the suspended particulate was filtered and examined non-destructively by light microscopy first, to characterize the material. A low magnification stereo microscope image of the filtered white particulate is shown in the image above. From this image, biological tissues were ruled out, and the material was observed to be crystalline. Polarized light microscopy (PLM) was used to analyze the sample next. From this examination, the material showed birefringence as shown in the PLM image on the right. The PLM Image Stereo Microscope image suspect material showed optical properties and morphology dissimilar to common carbonates and sulfates. It was determined to be a birefringent crystalline material, but it could not be identified using only PLM methods. Therefore, analysis using scanning electron microscopy with energy dispersive x-ray spectroscopy (SEM-EDS) would have to be performed to obtain further information about the suspect material.

Energy Dispersive X-Ray Spectroscopy (EDS): While in a Scanning Electron Microscope (SEM), samples are exposed to high energy electrons in a vacuum, which generates X-rays through secondary electron transitions. Variations in electron configuration specific to each element generate different energy electrons, and thus different signature energy peaks, indicating which elements are present in the sample. Analysis is performed only on areas which are exposed to the electron beam, facilitating precise control of the analyzed area. This means the composition of very small areas or particles in a sample can be taken. Since EDS is performed in the SEM chamber, a quick and easy interrogation of the surface materials as viewed on the SEM is possible. This can be expanded to include the entire sample, please see our Elemental Mapping page. Additionally, relative amount of the elements present can be calculated, generating composition percentages.

Scanning electron microscopy with energy dispersive xray spectroscopy (SEM-EDS) was used to identify the particles. The SEM showed an elevated concentration of iron and iron oxide in the impacted areas. The backscatter electron (BSE) image which correlates brightness in the image with atomic density, highlighted the iron particles that were embedded in the tile and the EDS spectrum confirms the PLM Image chemical composition of these higher density particles.

Dust samples were analyzed using polarized light microscopy (PLM) to provide percentages of the particle types present in the samples. MVL was able to determine that there was significant loading of glass fibers in the dust samples with the likely source being contractor’s work in the attic which involved disturbing the fiberglass insulation. The image on the right shows a few distinct glass fibers with a binder material adhered to them, consistent with fiberglass insulation. Discover extra details at https://microvisionlabs.com/.
