# Laboratory analysis of surface deposits and particles

## You observe the formation of particles and deposits on the surface of your materials and you wish to analyze them?

### What is a particle/deposit?

First of all, a particle is a very small, sometimes residual, part of a chemical substance or material. Small particles are often very small and may not be visible to the naked eye. On the other hand, a deposit is a thin layer covering your materials.

### Why analyze your particles and deposits?

The presence of particles and deposits on the surface of your materials is generally abnormal and characteristic of a failure. Indeed, this can have several consequences such as the formation of corrosion, a problem of adhesion, an interaction with a content, etc…

Thus, the analysis of your particles and deposits by a specialized laboratory allows you to determine their origin and finally, to optimize your materials.

## FILAB supports you in the analysis of deposits and surface particles of your materials

For more than 30 years, our laboratory FILAB has had the experience and the [specific analytical equipment](https://filab.fr/en/our-technical-resources.md) to support industrial companies in surface and deposit analysis through tailor-made assistance.

Indeed, through our three levels of services: analysis, expertise and R&D support, FILAB assists companies of all sectors and sizes.

In addition, our skills and complementarity in chemistry and materials ensure a complete and reliable expertise for all your surface chemistry analysis needs
