Microhardness testing company in US 2021
Microscopy laboratories in US in 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.
Energy Dispersive X-Ray Spectroscopy (EDS): While in a Scanning Electron Microscope (SEM), samples are exposed to high energy electrons in a vacuum, which generates X-rays through secondary electron transitions. Variations in electron configuration specific to each element generate different energy electrons, and thus different signature energy peaks, indicating which elements are present in the sample. Analysis is performed only on areas which are exposed to the electron beam, facilitating precise control of the analyzed area. This means the composition of very small areas or particles in a sample can be taken. Since EDS is performed in the SEM chamber, a quick and easy interrogation of the surface materials as viewed on the SEM is possible. This can be expanded to include the entire sample, please see our Elemental Mapping page. Additionally, relative amount of the elements present can be calculated, generating composition percentages.
Do you do any animal testing? No. Do you analyze any tissue samples or blood samples? No. We do not do any blood analyses and we are not set up to prepare tissue samples. What are some of the cool samples you have looked at under the scanning electron microscope? We have seen 10,000 year old Wolly Mammoth hair, meteorites, an artificial heart valve, civil war bullets, insulin pumps, rare colonial coins, a kidney stone, and a few things we can’t talk about. But some of the more mundane samples, like wood or salt crystals, have proven to be extremely interesting subjects to image. See even more info at microvision labs ma. ?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).
The client was able to obtain a comprehensive sampling of the state of the soldering process from the new manufacturer at a very reasonable cost. Rather than acquiring a mass of images, electrical test print outs, or low resolution optical pictures, the client received a comprehensive report detailing the relevant findings of the analysis on the boards from the new manufacturer. The solder joints in this study showed good bond integrity as well as excellent intermetallic layers. These findings allowed for the validation of the new manufacturer and their process which allowed for the clients device production to resume. The QC Engineers were very pleased with the customer service, analysis, pricing and quick turnaround time of this project.
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.
