Microhardness testing providers in Chelmsford, MA 2021? 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.
Translucent or transparent coatings on metallic or semi-conductor substrates are very difficult to image due to their reflective nature. Nomarski/DIC imaging is an effective method for accentuating differences in thickness, density or the optical index in these cases. This analysis enhances and highlights subtle features with brilliant color gradients and captures them with a high resolution digital imaging system. Let us bring out your sample’s hidden features.
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. See additional info at https://microvisionlabs.com/. MicroVision Laboratories, Inc. has been providing extensive expertise in micro-analytical techniques (FE-SEM, SEM, EDS, XRF, FTIR testing, PLM, X-Ray Imaging, DIC) and sample preparation since 2003. Our cutting edge, high-performance equipment combined with our solutions-focused customer service provide critical solutions for clients hailing from a broad range of industries ranging from medical to semiconductor, and from environmental to textile.
Examining the sample with a polarized light microscope (PLM), it was darker and coarser than expected for a mold sample. The dust appeared to be a closed cell, synthetic blown foam material, and all from the same source. The black color was likely due to pigment particles added to color the foam. Fourier Transform Infra-Red spectroscopy was performed on the foam particles. The spectrum showed a mixture of spectral features, associated with vinyl acetates, polyurethane, and cellulose or other sugar-like polymers. Based on these features, a common urethane acetate foam was determined as the likely source material.
Also, the color EDS map highlights the iron particles in the mineral filled PVC floor. These iron particles were concentrated in areas were the tile showed signs of impact which indicated some metallic object impacted the tile leaving behind small particles and over time the materials oxidized which created darker spots in the tile. 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.
