Sem/eds analysis providers in Chelmsford right now? 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 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.
How do I submit a sample or a set of samples? To submit a sample or set of samples, please see the page How to Submit Samples. What if I believe my samples are hazardous? We are not equipped to handle or dispose of every kind of hazardous material. Please call us before sending in any potentially hazardous samples. In cases where we are able to analyze your harzardous samples we may not be able to dispose of them and therefore we will return them to you. Read a few extra info on visit their site. ?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.
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.
The client was contacted with the results, and was curious as to what the source of these particles might be. After consulting with the office manager, it was determined that some pieces of furniture present had relatively significant amounts of direct water exposure, and were subsequently dried a number of times during remittance construction. Inspection of these pieces of furniture showed that they had high density, close packed foam cushions of a type similar to the particles observed in the surrounding area, which had been broken down by the repeated wet/dry cycle.
