Particle Sizing and Particle Size Analysis

The majority of industrial materials and products consist of solids and powders. Particle sizing, size distribution and particle shape are important physical characteristics that highly influence the behavior during processing and handling of powders, like flowability, transport, caking, and storage. Laboratory particle sizing analysis by characterization of size distribution and shape is a strong tool in R&D and Quality Control environment and important in various areas such as: crystal growth, ceramic and alloy properties, emulsions stability, taste experience, catalyst activity, paint appearance and performance, wastewater management, and so forth. Accordingly, these particle size analysis techniques are frequently practiced in pharmaceutical industry, food and feed industry and the chemical and petrochemical industry.

Closely related to particle sizing analysis is the droplet size distribution of sprays, nebulizers and other aerosols. Droplet size analysis is mainly used to optimize nozzle design, enhance inkjet printing technology, restrict excessive use of pesticides and increase medicine effectiveness. Smaller sized droplets can provide a much higher effectiveness if they reach the right targets in the body.

Various modern techniques such as Laser Diffraction, Electrical Sensing Zone, Photon Correlation Spectroscopy, Image Analysis, and Scanning Electron Microscopy are available in our analysis laboratory for particle size analysis. Our laboratory also employs more conventional particle sizing methods such as Sedimentation and Sieve Analysis for particle size analysis.

The presence of all these techniques enables to obtain particle size distribution information over a very wide range of particle sizes from nanometers to millimeters and depending on the particle size analysis technique this can be achieved with very high particle size resolution.
