Eds analysis providers in Chelmsford 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.
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 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. Discover extra info on here. ?MicroVision Labs is owned and operated by a career microscopist, John Knowles, who understands the needs of our clients. Our emphasis on helping our clients solve problems, not just providing data, sets us apart from other labs. We have the technology and knowledge to find answers to your most difficult challenges, helping you succeed at every step. Can I come in to see my samples analyzed? Yes, our clients are always welcome to come in while their samples are being analyzed. For much of the work we do, it is mutually beneficial for our clients to be present to help direct their project since they can provide expertise about their samples. Some of the services we provide such as polished cross sections have time consuming steps making it impractical for a client to stay to watch everything. In those cases it is recommended that you come in initially to explain what you need done and come back at a later time to see the finished product.
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.
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. See additional info at this website.
