# Laboratory analysis using Laser Granulometry

## Your needs: analyse the granulometry of a powder, grain or particle using a laser granulometer

### What does laser particle size analysis involve?

- **Measure the size of particles** present in a sample to understand their nature.
- **Measure the quality and conformity of powders** used in a wide range of sectors (chemicals, pharmaceuticals, medical devices, etc.), particularly in additive manufacturing.

 This type of analysis can be carried out by laser granulometry (liquid or dry method), by sieving or by sedimentation.
## Our solution : to study the particle size distribution of samples using laser granulometry

### Why call on FILAB for laser particle size analysis?

## FAQ

 What is the purpose of a particle size analysis?
L'analyse granulométrique est une méthode utilisée pour mesurer et caractériser les particules en termes de taille, de forme, de surface, de porosité et d'autres caractéristiques physiques. Elle permet d'identifier les types de matériaux ou de particules présents dans un échantillon et d'évaluer la manière dont ils interagissent les uns avec les autres. Ces informations peuvent être utilisées à diverses fins, notamment pour garantir la sécurité des produits et le contrôle de la qualité, pour mettre au point des procédés industriels utilisant la technologie des particules pour mélanger, séparer ou enrober des matériaux, ou pour étudier le comportement des systèmes particulaires. L'analyse de la taille des particules peut également permettre de comprendre comment différentes particules peuvent affecter les performances de filtration ou comment deux poudres différentes peuvent se mélanger. L'analyse granulométrique peut être utilisée pour mesurer les taux de sédimentation et différencier les différentes tailles de particules avant de les soumettre à d'autres analyses. 

 What is the difference between particle size analysis by sieving and particle size analysis by sedimentation?
Particle size analysis by sieving is a physical process that uses sieves to separate particles according to their size. Particles are poured onto a sieve and the sieve is gently shaken, allowing the smaller particles to pass through while the larger particles remain on top. This method works well for measuring the size of small particles, but is not practical for larger particles.

Particle size analysis by sedimentation uses centrifugal force to separate particles according to their specific gravity. Samples are placed in a centrifuge and spun at high speed until the heaviest particles settle to the bottom of the tube or container. This method is more accurate for large particles than sieving, as it separates them according to their actual weight rather than just their size.

 What business sectors might be interested in particle size analysis?
Particle size analysis (particle size analysis) is widely used in a variety of industries, including pharmaceuticals, biotechnology, cosmetics, food processing, agriculture and petrochemical production. Pharmaceutical companies use particle size analysis to guarantee the quality of their products by determining the particle size distribution of the active ingredients in tablets or capsules. The food industry uses particle size analysis to measure the particle size distribution of cereals or flour for cooking purposes. Particle size analysis can be used in agriculture to monitor soil erosion and sedimentation rates. Petrochemical companies can also use particle size analysis to study the emulsification or dispersion behaviour of their products.

 Is FILAB accredited to ISO 13320?
Yes — FILAB is ISO 17025-accredited by COFRAC for particle size analysis of metallic powders and all other multi-scale powders, using either wet or dry methods, in accordance with ISO 13320 (and PE 2.0.31).

 What additional powder characterisation methods complement granulometry testing?
[XRD](https://filab.fr/en/our-technical-resources/x-ray-crystallography-laboratory-xrd.md) or [SEM-EDX](https://filab.fr/en/our-technical-resources/laboratory-analysis-sem-scanning-electron-microscopy.md) powder analysis: complementary to granulometry testing for identifying the crystallographic composition (XRD) and particle morphology (SEM-EDX).

[BET surface area analysis](https://filab.fr/en/our-technical-resources/laboratory-analysis-bet.md): essential for correlating particle size, porosity and reactivity during granulometry testing.

[ination analysis](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-particulate-contaminant.md): detection and identification of unwanted particles in a matrix, often combined with granulometry testing to control product quality.

[Hydroxyapatite powder characterisation](https://filab.fr/en/our-services/our-expertise-services/laboratory-biocompatibility-testing/hap-powder-characterization.md)(NF ISO 13779-3): includes granulometry testing and chemical analysis to ensure regulatory compliance and biocompatibility.

[Nanomaterial characterisation](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-nanomaterial.md): assessment of nanoparticle size and distribution, complementing laser diffraction granulometry testing for nanoscale materials.
