Xrf analysis laboratories in Chelmsford, MA? Light microscopy allows for the examination of optical and structural properties of a variety of samples. Optical properties such as polarization and birefringence help to differentiate between fibers, minerals, ceramics, biological materials and opaque materials including paints, coatings and metallic particles. This allows a wide range of particles to be quickly and effectively identified and quantified by an experienced analyst.
The SEM was used to examine the crystal morphology, and the EDS spectrum showed primarily carbon and oxygen, with small amounts of nitrogen and phosphorous. This indicated an organic material as the primary component. Because the SEM-EDS analysis showed the material was primarily a carbon based organic crystalline material, a Fourier transform infrared spectroscopy (FTIR) examination was performed on the suspect material. This analysis provides necessary information about the functional groups of the organic material in order to identify the unknown organic.
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.
How do I submit a sample or a set of samples? To submit a sample or set of samples, please see the page How to Submit Samples. What if I believe my samples are hazardous? We are not equipped to handle or dispose of every kind of hazardous material. Please call us before sending in any potentially hazardous samples. In cases where we are able to analyze your harzardous samples we may not be able to dispose of them and therefore we will return them to you. Find a few more details at elemental mapping.
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.
