Sem/eds analysis providers by MicroVision Laboratories, Inc.? ?We partner with companies in all phases of product development and sales, including R&D, manufacturing, QC, advertising and failure analysis. Our laboratory offers a highly-trained and experienced staff utilizing a powerful set of analytical tools (SEM with EDS and backscatter detectors, Bruker X-Flash elemental mapping, X-Ray imaging, Micro-FTIR spectroscopy, Micro-XRF, light microscopy, cross sectioning/precision polishing and microhardness testing).
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.
What is your standard turnaround time (TAT) and can it be expedited? Our standard TAT is 5 to 10 business days. We can provide faster TATs on request with the following surcharges: – Same day to 24 hour rush is 100% surcharge – 2 day rush is 75% surcharge – 3 day rush is 50% surcharge – 4 day rush is 25% surcharge Rush requests must have prior approval otherwise we cannot guarantee turnaround times.
The diameter, perimeter, shape and aggregation patterning of particles are often of interest with manufactured or naturally occurring materials. Our PSA method is useful to measure and document the morphology and distribution of a sample. Whether you have particles, pores or film coatings, we can accommodate your project needs.

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.
