Laboratory analyses using Laser Granulometry
Your needs : to measure the particle size distribution of a powder
Granulometric analysis is used to measure the size of particles found in a sample, with the aim of understanding their nature.
This kind of analysis is also used to evaluated the quality of powders used in various fields (chemistry, pharmaceuticals, medical devices…) and to ensure that they comply with standards, most notability as part of additive manufacturing.
These analyses are carried out using laser granulometry (wet or dry), sieving or sedimentation.
Our solution : to study the particle size distribution of samples using laser granulometry
To be able to fulfil an increasing number of requests, FILAB uses laser granulometry to measure the particle size distribution of dry or damp powders, with sample sizes varying from 3 to 10nm.
Laser granulometry is used to characterize organic, inorganic and even metallic powders used in pharmaceutical, cosmetic, chemical, ceramic and metallurgical (additive manufacturing) applications, all while abiding by regulatory standards such as ISO 13320.
FILAB is able to provide its technical know-how relating to granulometric analyses and can support you by fulfilling your needs for analysis and expertise :

Particle size analysis is a method used to measure and characterise particles in terms of size, shape, surface area, porosity and other physical characteristics. It can identify the types of materials or particles present in a sample and assess how they interact with each other. This information can be used for a variety of purposes, including ensuring product safety and quality control, developing industrial processes that use particle technology to mix, separate or coat materials, or studying the behaviour of particle systems. Particle size analysis can also help to understand how different particles can affect filtration performance or how two different powders can mix. Particle size analysis can be used to measure sedimentation rates and to differentiate between different particle sizes before further analysis.

Sieve sieve analysis 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 ones remain on top. This method works well for measuring the size of small particles, but is not practical for larger particles.
Sedimentation particle size analysis uses centrifugal force to separate particles according to their specific gravity. Samples are placed in a centrifuge and spun at high speed until the heavier particles settle to the bottom of the tube or vessel. This method is more accurate for large particles than sieving, as it separates them according to their actual weight rather than just their size.
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 ensure the quality of their products by determining the particle size distribution of active ingredients in tablets or capsules. The food industry uses particle size analysis to measure the particle size distribution of grain 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.
