CONTAMINATION CONTROL

Contamination control is critical in many product production phases. If there is a contamination problem, not finding the source could be very costly to your company. Everything is contaminated; it’s just a question of how much and by what. If it becomes a problem, we can help. Contaminants come from many sources, processes, raw products, equipment, facilities, and from the outside. With over thirty years' experience in cleanrooms and troubleshooting equipment, failures in the mining environment, we have worked from the sublime to the ridiculous. 

The image above is a sample of debris from a shop where welding, torch cutting, and high-speed grinding of iron is conducted. This scanning electron microscope image shows a couple of the broken magnetite spheres. The “hieroglyphic” texture of the surface of the spheres can also be seen here. The presence of magnetite spheres generally indicates that welding, iron torch-cutting, or high-speed abrasive forming (grinding) of iron is occurring in the nearby environment. They are also formed in much smaller quantity by a flint-type lighter.
