Sieving is a separation technique based on the difference in particle size. The sieve is responsible for retaining the larger particles. On top of size, other factors play a role in determining whether a particle will pass through the sieve or not; format of the particle whether the particle will fall where there is an opening or on the mesh of the sieve and surface humidity.

A molecular sieve is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can.As a mixture of molecules migrate through the stationary bed of porous, semi-solid substance referred to as a sieve (or matrix), the components of highest molecular weight ...
