Microscopy laboratories by Microvisionlabs.com? ?MicroVision Labs is owned and operated by a career microscopist, John Knowles, who understands the needs of our clients. Our emphasis on helping our clients solve problems, not just providing data, sets us apart from other labs. We have the technology and knowledge to find answers to your most difficult challenges, helping you succeed at every step. Can I come in to see my samples analyzed? Yes, our clients are always welcome to come in while their samples are being analyzed. For much of the work we do, it is mutually beneficial for our clients to be present to help direct their project since they can provide expertise about their samples. Some of the services we provide such as polished cross sections have time consuming steps making it impractical for a client to stay to watch everything. In those cases it is recommended that you come in initially to explain what you need done and come back at a later time to see the finished product.
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. See even more details at more info here.
The data indicated that a significant portion of the dust was from the insulation in the attic. The contractor had replaced a portion of duct work running to the master bedroom. During this replacement, fiberglass insulation was knocked into the ducting. The small glass insulation fibers were spread through the AC ducts and settling out of the air throughout the house. The client was relieved to know what was causing their skin irritation and the significant dust build up. Using the results garnered from the analysis from MicroVision Labs they were able to have the contractor clean out the duct work and act to prevent further spread of the insulation fibers and properly clean up the settled dust in the house that was the cause of the homeowner’s skin irritation.
Do you do any animal testing? No. Do you analyze any tissue samples or blood samples? No. We do not do any blood analyses and we are not set up to prepare tissue samples. What are some of the cool samples you have looked at under the scanning electron microscope? We have seen 10,000 year old Wolly Mammoth hair, meteorites, an artificial heart valve, civil war bullets, insulin pumps, rare colonial coins, a kidney stone, and a few things we can’t talk about. But some of the more mundane samples, like wood or salt crystals, have proven to be extremely interesting subjects to image.
SEM is a powerful surface microscopy method which allows for high resolution images to be obtained on a wide range of samples. A focused beam of electrons sweeps across a sample surface and an image is created from the scattered electrons. The electron beam allows for the accurate imaging of features below the resolution limit of visible light. The acquired pictures retain good depth of field, resulting in excellent three-dimensional images. Variations in beam parameters can be made in order to highlight variations in density in the target sample, show extremely fine surface features, and illustrate texture in sample surface coatings. MicroVision Labs has multiple fully-operational SEMs, Bruker X-Flash EDS detectors and mapping technology, backscatter electron (BSE) imaging, and large chamber capabilities. These provide a full suite of microscopy services for all of your analytical needs. Explore more details at https://microvisionlabs.com/.
Conclusion: Based on the analytical report, the client was able to demonstrate that the particles were consistent with a common aspirin tablet. When the end customer was approached with this report, they remembered that their spouse had taken an aspirin earlier that morning, and had likely used the bottle of water in question to do so. Based on this, the customer was happy, the manufacturing client was satisfied, and the sample was maintained – undestroyed should someone need to examine the sample again or do any more esoteric testing. For an affordable price, the client was able to get piece of mind, and gather information from a very wide range of testing methods quickly and accurately.
