Eds testing company in the USA 2021? 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.
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.
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. See even more details at official website.
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.
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.
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.
