Laboratory analyses using Laser Granulometry

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.
