Sem/edx providers by MicroVision Laboratories 2021? 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.

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.

A client responsible for maintaining the facilities in a public school district called with concerns of a possible mold problem. Areas with high foot traffic, especially those where students tracked water in, were showing dark black spots in the floor tiles. Aggressive cleaning and buffing of the floor would remove the problem for a while, but after several few weeks, the problem resurfaced. The facilities management staff was convinced it was mold related, but sending samples, swabs, and air grabs to a mold lab for culturing showed no sign of fungal structures on the tiles.

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.

In Fourier Transform Infrared (FTIR) Spectroscopy samples are subjected to a broad frequency spectrum of infrared light which spans the energies of intramolecular vibrations, especially in organic compounds. The pattern and intensity of frequencies absorbed by a sample are plotted, which gives structural information about the chemical bonding state of the material. Organic compounds, which are generally very similar from an elemental standpoint, can be separated and identified using these structural fingerprints. Explore a few extra info at this website.
