Fisher Sub Sieve Sizer
General Description
1. Average Particle Size Analyzer (Fisher Sub-Sieve Sizer) is an apparatus using a gas-permeability method for determination of the average particle diameter of powders.
2. Particle sizer operates on air permeability principle. Result is read directly from multi-curve chart on front of instrument after simple alignment of indices. Complex calculations are ignored to get the result. 3. A sample, equal in weight (grams) to the true density of the material, is compacted between two porous plugs in a metal tube, to a known porosity.
4. Air or a suitable gas, under a constant pressure head, is passed through the compressed sample, and rate of flow is measured by a calibrated flowmeter.
5. The average particle diameter of the powder is indicated directly on a self-calculating chart by the liquid height in one arm of the flowmeter tube...
6. No dispersion is required, and the results are unaffected by particle shape.
