Detecting and identifying impurities

Your needs : to identify and characterize an impurity found in a material or in a formulation

The behavior of an industrial substance is directly linked to the characteristics and the purity of the materials used to produce it. In light of this, monitoring the conformity of the materials being used is a key step of the production process.

The presence of particulate matter, of an unknown deposit, the appearance of unknown spikes, etc. These represent cases of non-conformities which can stop a product from going on the market. For this reason, industrialists regularly call on analytical laboratories to identify and characterize any impurities found to be in their materials or formulations.  

Our solution : to provide you with our skills and our analytical tools, adapting them to your impurity related challenges.

With an analytical fleet spread over 2100m² and a team made up of doctors and engineers, FILAB can assist industrialists in detecting and identifying impurities in their products.

To overcome these challenges with precise and reliable results, FILAB offers a wide range of analytical techniques, adapted to all types of materials :
