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.
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. Discover extra details on microvision. MicroVision Laboratories, Inc. has been providing businesses, consultants and other testing laboratories with expert microscopy and analytical services since 2003. Our client base covers a broad spectrum of industries including semi-conductors, aerospace, electronics, biomedical, ceramics, optics, pharmaceuticals, mineralogy, metallurgy, thin films, environmental, membranes filtration and industrial hygiene.
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.
A device manufacturer had a product that involved a few different boards with varying components. There were circumstances that caused the need for a change in manufacturers of one of the boards. Due to this change, the device production at this facility would be shut down until the boards from this new vendor were validated. The Quality Control department required that an inspection of the solder joints of some of the components on the board be analyzed in order to determine whether this new board manufacturer met their specifications. If the desired specifications were met and no issues were found during the inspection of the joints then production of the devices could resume.
