Xrf analysis providers by MicroVision Laboratories 2021? As indicated in the FTIR spectral comparison below, the suspect material showed a near perfect match for acetylsalicylic acid. Additionally, there was a small amount of dibasic phosphate present. It was determined that the material was likely acetylsalicylic acid with a phosphate binder – an aspirin. Therefore, from this analysis the suspect material in the bottle was likely a household aspirin tablet, broken apart and separated by the water. In order to confirm the identification, a few aspirin tablets from several common manufacturers were obtained, roughly ground, and soaked to allow for comparison. The optical morphology of the crystals, size range of the particles, association with the phosphate and FTIR spectrum all were consistent with the original suspect material. A report detailing the methods and findings in full narrative form was rendered to the client.
Using light microscopes to examine the optical and structural properties of samples is one of the oldest and most useful analytical techniques. MicroVision Labs has several high magnification microscopes, including a powerful Zeiss Axiotech microscope capable of 1800x optical magnification, with additional digital magnification, allowing for visualization of sub-micron structures. PLM allows for the identification of a wide range of particles through the examination of the internal birefringence, or variation in optical indices, within a sample.

Discover a few extra info on microvision labs ma. ?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.
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. Find more info at https://microvisionlabs.com/.
