Eds analysis and elemental mapping laboratories with Microvisionlabs.com? 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.
SEM allows for high magnification surface examinations of a wide variety of samples. Providing brilliant resolution as well as incredible depth of field, the SEM, especially when combined with EDS, is often considered the most powerful analytical tool of our time. Let us show you why. X-ray imaging allows us to look inside of a device without opening it up. This real-time nondestructive inspection technique can be used on packaged electronic devices to one of a kind ancient artifacts. With rapid image acquisition and high sample throughput, X-ray imaging is particularly useful for sample screening and quality control issues. It is also often the first step in failure analysis and polished cross section projects.
Do you give lab tours? Yes, we routinely give lab tours to our clients and potential clients. Please call and we would be happy to schedule a tour for you and your co-workers. Do you have other locations around the country? We do work for companies all across the United States, with one laboratory which is located in Chelmsford, Massachusetts. Did MicroVision Labs ever operate under a different company name? No, we have always been MicroVision Laboratories, Inc. Our founder, John Knowles, used to work for another laboratory that underwent several name changes (Eastern Analytical Laboratories, Industrial Environmental Analysts, American Environmental Network, Severn Trent Laboratories, and EMLab P&K Billeria) and was located nearby in Billerica. When that laboratory was closed in 2008, John hired a few of the remaining analysts and acquired its equipment, client list and phone number. Discover even more info at go to website.
The profile of the flow of the solder at these bonds was documented using the SEM with backscatter imaging, which correlates brightness in the image with atomic density. Some voids were found in the solder as shown the SEM image. An EDS spectrum of the solder was acquired which showed that the solder was a tin/lead (80/20) solder. The EDS map clearly shows the copper wire and copper pad (red) with the tin lead solder (light blue) that appears to have flowed well and made a good bond between the copper elements. This map also shows the fiberglass bundles that add structural integrity to the board.
MicroVision Laboratories, Inc. has been providing businesses, consultants and other testing laboratories with expert microscopy and analytical services since 2003. Our client base covers a broad spectrum of industries including semi-conductors, aerospace, electronics, biomedical, ceramics, optics, pharmaceuticals, mineralogy, metallurgy, thin films, environmental, membranes filtration and industrial hygiene.
A client responsible for maintaining the facilities in a public school district called with concerns of a possible mold problem. Areas with high foot traffic, especially those where students tracked water in, were showing dark black spots in the floor tiles. Aggressive cleaning and buffing of the floor would remove the problem for a while, but after several few weeks, the problem resurfaced. The facilities management staff was convinced it was mold related, but sending samples, swabs, and air grabs to a mold lab for culturing showed no sign of fungal structures on the tiles.
