Particle size analysis laboratories in Chelmsford, MA? SEM allows for high magnification surface examinations of a wide variety of samples. Providing brilliant resolution as well as incredible depth of field, the SEM, especially when combined with EDS, is often considered the most powerful analytical tool of our time. Let us show you why. X-ray imaging allows us to look inside of a device without opening it up. This real-time nondestructive inspection technique can be used on packaged electronic devices to one of a kind ancient artifacts. With rapid image acquisition and high sample throughput, X-ray imaging is particularly useful for sample screening and quality control issues. It is also often the first step in failure analysis and polished cross section projects.
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 client was able to obtain a comprehensive sampling of the state of the soldering process from the new manufacturer at a very reasonable cost. Rather than acquiring a mass of images, electrical test print outs, or low resolution optical pictures, the client received a comprehensive report detailing the relevant findings of the analysis on the boards from the new manufacturer. The solder joints in this study showed good bond integrity as well as excellent intermetallic layers. These findings allowed for the validation of the new manufacturer and their process which allowed for the clients device production to resume. The QC Engineers were very pleased with the customer service, analysis, pricing and quick turnaround time of this project.
Do you give lab tours? Yes, we routinely give lab tours to our clients and potential clients. Please call and we would be happy to schedule a tour for you and your co-workers. Do you have other locations around the country? We do work for companies all across the United States, with one laboratory which is located in Chelmsford, Massachusetts. Did MicroVision Labs ever operate under a different company name? No, we have always been MicroVision Laboratories, Inc. Our founder, John Knowles, used to work for another laboratory that underwent several name changes (Eastern Analytical Laboratories, Industrial Environmental Analysts, American Environmental Network, Severn Trent Laboratories, and EMLab P&K Billeria) and was located nearby in Billerica. When that laboratory was closed in 2008, John hired a few of the remaining analysts and acquired its equipment, client list and phone number. Find more info at imaging technology.
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.
