Methods of Particle Size Analysis

The particles are small solid materials and there is in almost every substance or matter, the size and structure of particle are measured for different purposes. Larger size particles are settling better, whereas smaller particle is less. Particle size mostly affects the proprieties of the material such as their dissolution, solubility, and stability etc.
Particle size is a common word and holds a broad variety of sizes of substance, there are several methods are used for particle size determining, only a some are fundamental, that is, do not need calibration through other methods, microscopic method is one of these, However it is used as a regular method of measurement in many areas.
There are several methods used for the particle size analyze, besides laser diffraction. Sieving is the oldest method that still generally used for relatively large particles size ie. > 1mm and for measuring small size particles is. < 0.5um, the Dynamic Light Scattering is the simple methods to use. 
Here are mentions some methods for Particle size determination are as follows.

1. Optical microscopy
2. Sieving method
3. Sedimentation method
4. Coulter counter method
5. LASER Diffraction method
