The scan from left to right shows a high tin concentration (green line) while areas of higher lead concentrations (blue line) were not intersected by the line scan. At the interface between the tin/lead solder and copper (red line), there is a mixture of the solder and copper which is the intermetallic layer. The EDS Map provides a nice visual mixture of colors which shows the intermetallic layer while the line scan clearly shows the intermetallic with the elemental graph.
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.

The client was able to determine the source of the black dust was due to the mechanical breakdown of the foam cushions in the impacted room, and not from mold or mildew growth. The experienced analysts at MicroVision Labs were able to differentiate the foam materials from either blown cellulose or urethane foam insulation or air filters, allowing for the client to easily remove the problem cushions.
How do I submit a sample or a set of samples? To submit a sample or set of samples, please see the page How to Submit Samples. What if I believe my samples are hazardous? We are not equipped to handle or dispose of every kind of hazardous material. Please call us before sending in any potentially hazardous samples. In cases where we are able to analyze your harzardous samples we may not be able to dispose of them and therefore we will return them to you.
The unique properties of birefringence allow for the differentiation of fibers, minerals, ceramics, and other biological materials. Particles can therefore be identified and comparatively quantified, resulting in the characterization of the components of a sample. Complimentary optical techniques such as Nomarski/DIC, bright field and dark field imaging add to the amount of information our Optical Analysts can obtain from your samples. Additionally we have a range of light sources and filters to outfit our stereo microscopes for fluorescent microscopy. Read even more details at here.
