Advantages and Disadvantages Of Different Particle Sizing Methods
For user who wants to do particle size analysis of his specific powders, knowing advantages and disadvantages of particle size analysis method is significant to choice among instruments and finally successfully buy right instrument.
- Air Permeability Fisher Method
A fisher sub sieve sizer works on air permeability fisher method. Compared to other particle sizing method, it has advantage of
A:low cost of instrument, sample dispersion not an issue, testing on magnetic powders or hard alloy capable, directly read particle size.
D:only average particle size available, particle size distribution unobtainable

- Sieve Analysis
A:Advantages of the sieve analysis especially advanced air jet sieve analysis include fast and easy handling, low instrument cost, accurate and reproducible particle sizing results, short anlaysis time and the possibility to separate particle size grades or fractions by meshes. As a result air jet sieve method is a widely accepted alternative analysis methods using laser light or image processing method.
