Specific surface area of particle
There are several methods for measuring particle size and particle size distribution. Some of them are based on light, other on ultrasound, or electric field, or gravity, or centrifugation. The use of sieves is a common measurement technique, however this process can be more susceptible to human error and is time consuming. Technology such as dynamic image analysis (DIA) can make particle size distribution analyses much easier. This approach can be seen in instruments like Re… WebParticle Characterization – Micropore Analysis by Gas Adsorption – Part 2: Evaluation by Isotherms Comparison ...
