Particle size distribution field scan techniques

Field Scanning Methods In these techniques, the particles to be measured are examined collectively, and the signal from the assembly of particles is deconvulated to generate a size distribution. 

It is convenient to divide particle size measurement techniques involving the interaction between particles and an external field into two categories, stream scanning and field scanning. In the former, particles are examined one at a time and their interaction is taken as a measure of their size. In the latter, the interaction of an assembly of particles is interpreted in terms of the size distribution of the assembly. 

The dimensions, shape, aspect ratio, and other morphology characteristics influence the macroscopic properties of the materials. The microstmcture of particles is frequently used to explain the viscoelastic, electric, magnetic, and optical properties. In the field of composites, microscopy is essential to measure the shape and size of particle filler inside of the polymer, but it is important to determine particle distribution, segregation, and characteristics of the interface, hi the field of colloidal polymers, the properties of particles can be studied to explain the stability, rheology, color, and coalescence. The main techniques used to characterize the microscopic stracture of polymers are scanning electron miaoscopy (SEM), TEM, scanning probe microscopy (SPM), and their related techniques.
