# Laboratory for surface cleanliness analysis by SEM

## Your needs: controlling a product's surface cleanliness level

### Why analyze surface cleanliness with SEM?

For many application sectors (medical, [aerospace](https://filab.fr/en/sectors-of-activity/laboratory-analysis-aeronautics-aerospace.md), [automotive](https://filab.fr/en/sectors-of-activity/laboratory-analysis-automobile.md), electronics, etc.), a product’s functionality is directly linked to its surface.

Indeed, the presence of [chemical contamination](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-particulate-contaminant.md) or [particulate contamination](https://filab.fr/paroles-d-expert/metallurgie-fonderie-automobile/filab-vous-accompagne-dans-l-identification-de-pollution-particulaire.md) on the surface following the various stages of the manufacturing process can affect a material’s characteristics.

Thus, to guarantee a product’s surface cleanliness and therefore its quality, it is essential to implement a cleaning program specific to the substances involved in the manufacture of the item.

In addition, the preferred technique for assessing surface cleanliness is [Scanning Electron Microscopy (SEM-FEG)](https://filab.fr/en/our-technical-resources/laboratory-analysis-sem-scanning-electron-microscopy.md) coupled with an EDX microprobe.

This approach has the advantage of making it possible to map the spatial distribution of contaminants on the part’s surface.

## FILAB provides you with state-of-the-art SEM-FEG-EDX equipment to assess your surface cleanliness

From analysis to R&D, including expertise and validation of cleaning processes, the FILAB laboratory offers multisector expertise for several types of requests related to the surface cleanliness of materials:

## Our expertise
