Xrf analysis company in Chelmsford? We are proud to announce that MicroVision Labs is now accredited to the ISO/IEC 17025:2017 standard. This represents over a year of diligent effort from all of our staff to verify and validate our in house SOP’s and transform our quality management system to one that is compliant to this international standard. This certification requires that accredited labs demonstrate that they are competent and can produce technically valid data and results unlike other certifications such as ISO 9001:2015. This represents an obvious value to our clients.
The profile of the flow of the solder at these bonds was documented using the SEM with backscatter imaging, which correlates brightness in the image with atomic density. Some voids were found in the solder as shown the SEM image. An EDS spectrum of the solder was acquired which showed that the solder was a tin/lead (80/20) solder. The EDS map clearly shows the copper wire and copper pad (red) with the tin lead solder (light blue) that appears to have flowed well and made a good bond between the copper elements. This map also shows the fiberglass bundles that add structural integrity to the board. Explore additional details on microvision laboratories inc.
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.
What is your standard turnaround time (TAT) and can it be expedited? Our standard TAT is 5 to 10 business days. We can provide faster TATs on request with the following surcharges: – Same day to 24 hour rush is 100% surcharge – 2 day rush is 75% surcharge – 3 day rush is 50% surcharge – 4 day rush is 25% surcharge Rush requests must have prior approval otherwise we cannot guarantee turnaround times.
Energy Dispersive Spectroscopy (EDS) identifies the elements present in a sample by analyzing the X-rays generated by the electron beam of the Scanning Electron Microscope (SEM), making it an indispensable tool. Since X-rays are only generated from the area of the surface excited by the small electron beam, spectra of individual areas or particles can be obtained. Spectral information can therefore be generated for an entire field of view by scanning the beam, providing an elemental map. With the high count rate and excellent signal to noise ratio of our advanced QDD EDS detectors, high resolution data sets are collected and analyzed in minutes, rather than days. This elemental mapping technique allows our clients to immediately visualize the chemical landscape in their samples. Additionally, since the entire spectra is stored for each pixel, areas of interest that are identified later can be examined in detail, without ever having to re-image the sample. Other labs can’t touch the quality and visual impact of the elemental maps we produce here at MicroVision Labs. Find even more details at https://microvisionlabs.com/.
Approach: MicroVision Labs’ staff consulted with the client, and determined that, unfortunately, there could be a number of potential sources of a white material. Even before the bottle with the suspended material arrived, it was determined that there was less than 50 mL of water remaining, and likely less than a gram of material suspended in the water. The client was aware that this material could represent precipitated minerals from the source water, a polymer residue from the bottles, some form of biological tissue that might have formed despite sterilization procedures, or could very well represent some completely unforeseen foreign material. The issue facing the client is how to have the material tested, as most tests that they might request for one or the other of these known potential sources would destroy or alter the sample. Choosing a test was therefore something of a gamble, because if they tested for calcium (mineral precipitate) and it came up negative – that didn’t actually tell them what the powder was, just that it didn’t have any calcium. Based on this conversation, the non-destructive, specialized testing at MicroVision Laboratories was chosen as the best choice.
