Particle size analysis company with MicroVision Laboratories right now? The SEM was used to examine the crystal morphology, and the EDS spectrum showed primarily carbon and oxygen, with small amounts of nitrogen and phosphorous. This indicated an organic material as the primary component. Because the SEM-EDS analysis showed the material was primarily a carbon based organic crystalline material, a Fourier transform infrared spectroscopy (FTIR) examination was performed on the suspect material. This analysis provides necessary information about the functional groups of the organic material in order to identify the unknown organic.
Our membrane autopsy service uses a combination of microscopy techniques to examine filtration membranes and identify the elemental and chemical composition of any foulant materials present. This analysis also categorizes the degree of fouling and notes any other causes for poor performance, such as physical damage to the membrane surface. MicroVision Labs has extensive experience examining a wide variety of RO, UF and MF membranes, including hollow fibers, cartridge, spiral wound, and tubular membranes.
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. Find additional details at official website. 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).
An affected floor tile was submitted to determine if the previous mold testing had missed a source on the tile backing or mastic. Additionally, a new tile from the same manufacturing lot was submitted for comparison. The process of preparing and examining the sample and reference tile was documented. Areas with darkened surface features were imaged and then cut out and examined. While the dark spots looked very discrete when examined by eye, under top light polarized microscopy they appeared more diffuse at the outer edges. The darkest areas surrounded what appeared to be particles embedded in the surface.
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. Explore extra details on https://microvisionlabs.com/.
