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.
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.
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. Discover a few extra details on top light microscopy lab.

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.
Close examination of any possible defects or voids was undertaken at higher magnification. The voids did not appear to create any structural or conductivity issues. Additionally, the formation and contiguity of intermetallic bonds between the contacts and solder were shown using a combination of EDS line scan elemental spectroscopy and elemental mapping. The SEM image and the EDS map to the left show the intermetallic layer between the copper wire and the tin/lead solder via the mixture of the red copper and the blue tin.
