Xrf analysis company in Chelmsford, MA 2021? MicroVision Laboratories’ analytical experts were able to meet with the QC Engineers and develop an analytical plan as to which solder joints to cross section and inspect. The client not only wanted to determine if there were any significant issues with the solder joint but also determine that there was a good intermetallic bond between the tin/lead solder and the copper wires of the chip packages.
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.

Examining the sample with a polarized light microscope (PLM), it was darker and coarser than expected for a mold sample. The dust appeared to be a closed cell, synthetic blown foam material, and all from the same source. The black color was likely due to pigment particles added to color the foam. Fourier Transform Infra-Red spectroscopy was performed on the foam particles. The spectrum showed a mixture of spectral features, associated with vinyl acetates, polyurethane, and cellulose or other sugar-like polymers. Based on these features, a common urethane acetate foam was determined as the likely source material.
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 membrane autopsy service uses a combination of microscopy techniques to examine filtration membranes and identify the elemental and chemical composition of any foulant materials present. This analysis also categorizes the degree of fouling and notes any other causes for poor performance, such as physical damage to the membrane surface. MicroVision Labs has extensive experience examining a wide variety of RO, UF and MF membranes, including hollow fibers, cartridge, spiral wound, and tubular membranes.
