Particle size analysis and elemental mapping providers in US? Analysis and Results: The submitted bottle was examined for signs of interior distress, and the water from the bottle was removed and maintained. Some of the suspended particulate was filtered and examined non-destructively by light microscopy first, to characterize the material. A low magnification stereo microscope image of the filtered white particulate is shown in the image above. From this image, biological tissues were ruled out, and the material was observed to be crystalline. Polarized light microscopy (PLM) was used to analyze the sample next. From this examination, the material showed birefringence as shown in the PLM image on the right. The PLM Image Stereo Microscope image suspect material showed optical properties and morphology dissimilar to common carbonates and sulfates. It was determined to be a birefringent crystalline material, but it could not be identified using only PLM methods. Therefore, analysis using scanning electron microscopy with energy dispersive x-ray spectroscopy (SEM-EDS) would have to be performed to obtain further information about the suspect material.
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.
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. Read a few extra info on this link.
The desired chip packages were sectioned from the larger board, and placed in an epoxy mounting cup. The epoxy was mixed and allowed to harden. The resulting epoxy puck was cross sectioned and polished. The epoxy mounting and cross sectioning process gave precise, perfectly preserved cross sectional surfaces through the desired components and their solder bonds.

A client responsible for maintaining the facilities in a public school district called with concerns of a possible mold problem. Areas with high foot traffic, especially those where students tracked water in, were showing dark black spots in the floor tiles. Aggressive cleaning and buffing of the floor would remove the problem for a while, but after several few weeks, the problem resurfaced. The facilities management staff was convinced it was mold related, but sending samples, swabs, and air grabs to a mold lab for culturing showed no sign of fungal structures on the tiles.
