Sieving vs Laser Diffraction for particle size analysis

So, sieving is one of the oldest and simplest techniques and remains a useful method of separating particles based on their size. However, the time it takes to obtain accurate results, the poor resolution and problems associated with particle agglomeration and sieve blockage, have seen sieving being replaced in most industries.
