Microscopy company in the USA 2021? 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.
MicroVision Labs uses a brand new comprehensive LUMOS micro-IR that combines standard optical and polarized light microscopy. It also has sophisticated automation for a variety of IR spectral measurement techniques. Our LUMOS system is the first of its kind to be commissioned in the US and allows for particles down to 5um in diameter to be examined. This new instrument increases our ability to provide quality organic spectroscopy and enables sample mapping using special IR features with full automation for feature identification with quantifiable, traceable spectral measurement.
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. Explore more details on official website. We partner with companies in all phases of product development and sales, including R&D, manufacturing, QC, advertising and failure analysis. Our laboratory offers a highly-trained and experienced staff utilizing a powerful set of analytical tools (SEM with EDS and backscatter detectors, Bruker X-Flash elemental mapping, X-Ray imaging, Micro-FTIR spectroscopy, Micro-XRF, light microscopy, cross sectioning/precision polishing and microhardness testing).
The client was able to determine the source of the black dust was due to the mechanical breakdown of the foam cushions in the impacted room, and not from mold or mildew growth. The experienced analysts at MicroVision Labs were able to differentiate the foam materials from either blown cellulose or urethane foam insulation or air filters, allowing for the client to easily remove the problem cushions.
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.
