Sem/edx laboratories in the USA right now? 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.
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.
How do I submit a sample or a set of samples? To submit a sample or set of samples, please see the page How to Submit Samples. What if I believe my samples are hazardous? We are not equipped to handle or dispose of every kind of hazardous material. Please call us before sending in any potentially hazardous samples. In cases where we are able to analyze your harzardous samples we may not be able to dispose of them and therefore we will return them to you. Discover even more details at www.microvisionlabs.com. ?MicroVision Labs is owned and operated by a career microscopist, John Knowles, who understands the needs of our clients. 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 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.
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.
