# Identification of unknown deposit in laboratory

## Industrialists of any sector, you wish to identify an unknown deposit?

### What is a deposit?

The deposit is a particle that can be identified in isolation, or on the surface of a material. In the second case, the interactions and attacks of an environment can lead to the formation of residual particles on the surface of a material, which is called deposit or pollution.

A deposit or pollution can be **metallic**, **mineral** or **organic** in nature.

### Why identify an unknown repository?

The origin of a deposit is not always easy to identify: it can be present at the reception of the raw material, appear during the production process or be declared in its final environment. 

Moreover, the performance of a material is directly linked to its surface properties. Thus, the formation of a deposit or the presence of a pollution on a material can lead to a material [**failure**](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-failures.md), either visual (appearance of a stain, irregularities, color change…) or functional (adhesion problem, harmfulness…).

Thus, the identification of the chemical nature of an unknown deposit by a specialized laboratory makes it possible to define the actions necessary for its elimination before the marketing.

## FILAB offers you expertise and analysis techniques for unknown deposits

For more than 30 years, [FILAB](https://filab.fr/en/) has had the experience and specific [analytical equipment](https://filab.fr/en/our-services.md) to meet the needs of analysis of **unknown deposits** or pollution on a material.

Thanks to a tailor-made support, FILAB laboratory analyzes your problems and guides you until the interpretation of the results through the following expertise services:
