Xrf analysis laboratories by MicroVision Laboratories, Inc.? SEM is a powerful surface microscopy method which allows for high resolution images to be obtained on a wide range of samples. A focused beam of electrons sweeps across a sample surface and an image is created from the scattered electrons. The electron beam allows for the accurate imaging of features below the resolution limit of visible light. The acquired pictures retain good depth of field, resulting in excellent three-dimensional images. Variations in beam parameters can be made in order to highlight variations in density in the target sample, show extremely fine surface features, and illustrate texture in sample surface coatings. MicroVision Labs has multiple fully-operational SEMs, Bruker X-Flash EDS detectors and mapping technology, backscatter electron (BSE) imaging, and large chamber capabilities. These provide a full suite of microscopy services for all of your analytical needs. See even more details at look here.
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.
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.
Do you do any animal testing? No. Do you analyze any tissue samples or blood samples? No. We do not do any blood analyses and we are not set up to prepare tissue samples. What are some of the cool samples you have looked at under the scanning electron microscope? We have seen 10,000 year old Wolly Mammoth hair, meteorites, an artificial heart valve, civil war bullets, insulin pumps, rare colonial coins, a kidney stone, and a few things we can’t talk about. But some of the more mundane samples, like wood or salt crystals, have proven to be extremely interesting subjects to image.
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.
?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.
