Sem/edx services in Chelmsford, MA? Using light microscopes to examine the optical and structural properties of samples is one of the oldest and most useful analytical techniques. MicroVision Labs has several high magnification microscopes, including a powerful Zeiss Axiotech microscope capable of 1800x optical magnification, with additional digital magnification, allowing for visualization of sub-micron structures. PLM allows for the identification of a wide range of particles through the examination of the internal birefringence, or variation in optical indices, within a sample.
As indicated in the FTIR spectral comparison below, the suspect material showed a near perfect match for acetylsalicylic acid. Additionally, there was a small amount of dibasic phosphate present. It was determined that the material was likely acetylsalicylic acid with a phosphate binder – an aspirin. Therefore, from this analysis the suspect material in the bottle was likely a household aspirin tablet, broken apart and separated by the water. In order to confirm the identification, a few aspirin tablets from several common manufacturers were obtained, roughly ground, and soaked to allow for comparison. The optical morphology of the crystals, size range of the particles, association with the phosphate and FTIR spectrum all were consistent with the original suspect material. A report detailing the methods and findings in full narrative form was rendered to the client.
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.
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.

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.
