Particle size analysis laboratories in US 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.
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.
What is your standard turnaround time (TAT) and can it be expedited? Our standard TAT is 5 to 10 business days. We can provide faster TATs on request with the following surcharges: – Same day to 24 hour rush is 100% surcharge – 2 day rush is 75% surcharge – 3 day rush is 50% surcharge – 4 day rush is 25% surcharge Rush requests must have prior approval otherwise we cannot guarantee turnaround times. Discover additional details at see the microvision labs website. MicroVision Laboratories, Inc. has been providing businesses, consultants and other testing laboratories with expert microscopy and analytical services since 2003. Our client base covers a broad spectrum of industries including semi-conductors, aerospace, electronics, biomedical, ceramics, optics, pharmaceuticals, mineralogy, metallurgy, thin films, environmental, membranes filtration and industrial hygiene.
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.
The scan from left to right shows a high tin concentration (green line) while areas of higher lead concentrations (blue line) were not intersected by the line scan. At the interface between the tin/lead solder and copper (red line), there is a mixture of the solder and copper which is the intermetallic layer. The EDS Map provides a nice visual mixture of colors which shows the intermetallic layer while the line scan clearly shows the intermetallic with the elemental graph.
