Particle size analysis and elemental mapping laboratories by MicroVision Laboratories

Particle size analysis and elemental mapping laboratories with MicroVision Laboratories, Inc.? 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.

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.

What if I want a service not listed in your services list? At MicroVision Labs the list of services which we provide to our clients is constantly growing. So if you don’t see what you are looking for give us a call or use the Contact Us tab. Also don’t forget to check our Additional Services Page to see if it might be listed there. Can you identify a contamination or unknown for us? Yes, we call that an Unknown Material ID and we routinely work on that kind of project. We have a number of individual tests designed to classify unknown materials. When combined with our extensive suite of equipment, these tests allow us to identify virtually any material. Give us a call and talk to one of our knowledgeable staff for more information. Read even more info on Source.

Scanning electron microscopy with energy dispersive xray spectroscopy (SEM-EDS) was used to identify the particles. The SEM showed an elevated concentration of iron and iron oxide in the impacted areas. The backscatter electron (BSE) image which correlates brightness in the image with atomic density, highlighted the iron particles that were embedded in the tile and the EDS spectrum confirms the PLM Image chemical composition of these higher density particles.

MicroVision Laboratories, Inc. has been providing extensive expertise in micro-analytical techniques (FE-SEM, SEM, EDS, XRF, FTIR testing, PLM, X-Ray Imaging, DIC) and sample preparation since 2003. Our cutting edge, high-performance equipment combined with our solutions-focused customer service provide critical solutions for clients hailing from a broad range of industries ranging from medical to semiconductor, and from environmental to textile.

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.
