Laboratory analysis of particulate contaminations

Behind the idea of particulates or contaminants there is often the concept of size… A particle is only a tiny, sometimes residual, portion of a chemical substance or of a material.

Usually fine and minute, small particles cannot be seen by the naked eye.

Particulates or contaminants can often be analyzed :

• As part of a set of conformity analyses : verification of the size of particles or microparticles or even nanoparticles.
• As part of a more complex study, in the context of a contamination during the production process for example : particulates embedded in the surface of a metal part, dust contamination, cross contamination…
