Microscopy lab services by MicroVision Laboratories, Inc. in 2021? Problem: A client was a manufacturer of beverages, bottled water, and other drinks. They received a customer complaint through one of their distributors, which indicated that a customer had been drinking a bottle of water, and as they neared the bottom of the bottle, found a mysterious white powder floating in the bottom. The customer returned the bottle and complained. The client hoped to identify the powder so they could both satisfy their end customer, as well as identify any potential problems in their manufacturing or bottling process.

Light microscopy allows for the examination of optical and structural properties of a variety of samples. Optical properties such as polarization and birefringence help to differentiate between fibers, minerals, ceramics, biological materials and opaque materials including paints, coatings and metallic particles. This allows a wide range of particles to be quickly and effectively identified and quantified by an experienced analyst.

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).

An affected floor tile was submitted to determine if the previous mold testing had missed a source on the tile backing or mastic. Additionally, a new tile from the same manufacturing lot was submitted for comparison. The process of preparing and examining the sample and reference tile was documented. Areas with darkened surface features were imaged and then cut out and examined. While the dark spots looked very discrete when examined by eye, under top light polarized microscopy they appeared more diffuse at the outer edges. The darkest areas surrounded what appeared to be particles embedded in the surface.

Also, the color EDS map highlights the iron particles in the mineral filled PVC floor. These iron particles were concentrated in areas were the tile showed signs of impact which indicated some metallic object impacted the tile leaving behind small particles and over time the materials oxidized which created darker spots in the tile. The data indicated that a significant portion of the dust was from the insulation in the attic. The contractor had replaced a portion of duct work running to the master bedroom. During this replacement, fiberglass insulation was knocked into the ducting. The small glass insulation fibers were spread through the AC ducts and settling out of the air throughout the house. The client was relieved to know what was causing their skin irritation and the significant dust build up. Using the results garnered from the analysis from MicroVision Labs they were able to have the contractor clean out the duct work and act to prevent further spread of the insulation fibers and properly clean up the settled dust in the house that was the cause of the homeowner’s skin irritation.
