Particle size analysis laboratories with Microvisionlabs.com right now? 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.
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 client was able to determine the source of the black dust was due to the mechanical breakdown of the foam cushions in the impacted room, and not from mold or mildew growth. The experienced analysts at MicroVision Labs were able to differentiate the foam materials from either blown cellulose or urethane foam insulation or air filters, allowing for the client to easily remove the problem cushions.
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. Find additional details at Microvisionlabs.com/service/eds-elemental-analysis.

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. Explore additional details at this website.
