Eds analysis laboratories in US 2021? 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.
The unique properties of birefringence allow for the differentiation of fibers, minerals, ceramics, and other biological materials. Particles can therefore be identified and comparatively quantified, resulting in the characterization of the components of a sample. Complimentary optical techniques such as Nomarski/DIC, bright field and dark field imaging add to the amount of information our Optical Analysts can obtain from your samples. Additionally we have a range of light sources and filters to outfit our stereo microscopes for fluorescent microscopy.
What if I want a service not listed in your services list? At MicroVision Labs the list of services which we provide to our clients is constantly growing. So if you don’t see what you are looking for give us a call or use the Contact Us tab. Also don’t forget to check our Additional Services Page to see if it might be listed there. Can you identify a contamination or unknown for us? Yes, we call that an Unknown Material ID and we routinely work on that kind of project. We have a number of individual tests designed to classify unknown materials. When combined with our extensive suite of equipment, these tests allow us to identify virtually any material. Give us a call and talk to one of our knowledgeable staff for more information. Discover a few extra details at microvision labs chelmsford.

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.
MicroVision Laboratories’ analytical experts were able to meet with the QC Engineers and develop an analytical plan as to which solder joints to cross section and inspect. The client not only wanted to determine if there were any significant issues with the solder joint but also determine that there was a good intermetallic bond between the tin/lead solder and the copper wires of the chip packages.
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. Find additional details on microvisionlabs.com.
