Microscopy services in Chelmsford, MA right now? 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.
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.
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.

Our emphasis on helping our clients solve problems, not just providing data, sets us apart from other labs. We have the technology and knowledge to find answers to your most difficult challenges, helping you succeed at every step. Can I come in to see my samples analyzed? Yes, our clients are always welcome to come in while their samples are being analyzed. For much of the work we do, it is mutually beneficial for our clients to be present to help direct their project since they can provide expertise about their samples. Some of the services we provide such as polished cross sections have time consuming steps making it impractical for a client to stay to watch everything. In those cases it is recommended that you come in initially to explain what you need done and come back at a later time to see the finished product.
The desired chip packages were sectioned from the larger board, and placed in an epoxy mounting cup. The epoxy was mixed and allowed to harden. The resulting epoxy puck was cross sectioned and polished. The epoxy mounting and cross sectioning process gave precise, perfectly preserved cross sectional surfaces through the desired components and their solder bonds.
The client was contacted with the results, and was curious as to what the source of these particles might be. After consulting with the office manager, it was determined that some pieces of furniture present had relatively significant amounts of direct water exposure, and were subsequently dried a number of times during remittance construction. Inspection of these pieces of furniture showed that they had high density, close packed foam cushions of a type similar to the particles observed in the surrounding area, which had been broken down by the repeated wet/dry cycle.
