Sem/eds analysis laboratories in Chelmsford, MA? Translucent or transparent coatings on metallic or semi-conductor substrates are very difficult to image due to their reflective nature. Nomarski/DIC imaging is an effective method for accentuating differences in thickness, density or the optical index in these cases. This analysis enhances and highlights subtle features with brilliant color gradients and captures them with a high resolution digital imaging system. Let us bring out your sample’s hidden features.

As indicated in the FTIR spectral comparison below, the suspect material showed a near perfect match for acetylsalicylic acid. Additionally, there was a small amount of dibasic phosphate present. It was determined that the material was likely acetylsalicylic acid with a phosphate binder – an aspirin. Therefore, from this analysis the suspect material in the bottle was likely a household aspirin tablet, broken apart and separated by the water. In order to confirm the identification, a few aspirin tablets from several common manufacturers were obtained, roughly ground, and soaked to allow for comparison. The optical morphology of the crystals, size range of the particles, association with the phosphate and FTIR spectrum all were consistent with the original suspect material. A report detailing the methods and findings in full narrative form was rendered to the client.
Close examination of any possible defects or voids was undertaken at higher magnification. The voids did not appear to create any structural or conductivity issues. Additionally, the formation and contiguity of intermetallic bonds between the contacts and solder were shown using a combination of EDS line scan elemental spectroscopy and elemental mapping. The SEM image and the EDS map to the left show the intermetallic layer between the copper wire and the tin/lead solder via the mixture of the red copper and the blue tin.

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.
?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.
