Metody dyfrakcji laserowej
In various chemical
or physical and technical processes particles of the order of 1 μm up to a few mm in size appear, whose size distribution is decisive or important for the process. There are many technical examples like in food production, pharmacy, process engineering, fuel burning in turbines, motors etc., slurry burning, and cosmetics.
The laser diffraction particle sizer is capable to measure a particle size distribution from a collective of particles like a spray and to appropriately process, describe, and present it. The particle material may be solid or liquid in a gas or gas like air bubbles in a liquid. For the measurement it is only important, that the optical properties of the continuous and the dispersed phase are different.
The laser diffraction particle sizer offers the advantage of a fast and non invasive measurement in a wide range of particle sizes. Especially in case of sprays or suspensions this method has become a standard measurement tool.
