Particle-size analysis in the process environment

Laser Diffraction Methods Over the past 30 years laser diffraction has developed into a leading principle for particle-size analysis of all kinds of aerosols, suspensions, emulsions, and sprays in laboratory and process environments. 

In the polymer field, by the natiue of the production process, it is obviously important to be able to determine the end-point of the reaction. It is therefore necessary to choose a particle sizing technique that is appropriate and effective, one that can yield reliable and acciuate measures of the mean diameter and standard deviation of colloidal, mostly-submicron emulsions. In production environments it is particularly important that the size analysis instrument be fast, easy to use and able to reveal reproducibly the trend of particle growth diuing the polymerization reaction, so the operator can change production parameters based on these real-time results.
