# Powder analysis laboratory by BET according to the European Pharmacopoeia 2.9.26

## FILAB laboratory carries out powder analysis by BET according to European Pharmacopoeia 2.9.26

The specific surface area of a material refers to its actual surface area as opposed to its apparent surface area. It represents the total surface area per unit mass and is expressed in m²/g. In the case of powders, it makes it possible to assess the powder’s porosity.

The **chapter** *2.9.26. of* the European Pharmacopoeia describes the methodology for measuring specific surface area by gas adsorption.

## FILAB, ISO 17025 accredited laboratory by COFRAC for BET analysis according to EP 2.9.26

For more than 30 years, our FILAB laboratory has had the experience and the [analytical equipment](https://filab.fr/en/our-technical-resources.md) to support industrial companies today in the characterization of powders using various analytical techniques: [XRD](https://filab.fr/nos-moyens-techniques/analyse-et-caracterisation-des-materiaux-par-diffraction-des-rayons-x-drx-en-laboratoire/filab-caracterise-vos-mineraux-par-drx/), [SEM-EDX,](https://filab.fr/nos-moyens-techniques/laboratoire-d-analysis-par-microscopie-electronique-a-balayage-meb-edx/) [BET](https://filab.fr/en/our-technical-resources/laboratory-analysis-bet.md), [laser particle size analysis](https://filab.fr/en/our-technical-resources/laboratory-analysis-laser-granulometry.md)…
