The Micromeritics Sub-Sieve AutoSizer (SAS) II determines particle size, surface area, and powder bed porosity by air permeability.

Developed as a direct and modernized successor to the widely used Fisher Model 95 Subsieve Sizer (FSSS), the Micromeritics SAS II utilizes a built-in computer and touchscreen to perform measurements easily and quickly in a laboratory setting or on a production floor.  Data can be saved, printed, or exported electronically in spreadsheet or PDF formats.

The Micromeritics Sub-Sieve AutoSizer II generates “Fisher number” results highly consistent with that of its predecessor (the Fisher FSSS), using the built-in Fisher Mapping feature. This is a crucial point, as the air permeability technique and the FSSS have been used as a benchmark for decades in many industries. Many applications use historical data and quality control standards, and a modern source of comparable, repeatable results is necessary.

What is Air-Permeability Particle Sizing?

The air-permeability technique is well established for measurement of the Specific Surface Area (SSA) of a sample powder. The SSA measured by this technique has been found to be a useful parameter in various industries such as pharmaceutical, metal coatings, paints, and even geological samples.

The MIC SAS II utilizes dual pressure transducers to measure pressure drop across a packed bed of powder. By varying the sample height and porosity while controlling the flow rate of air through the sample, the SSA and average particle size can be determined using the Kozney-Carmen equation.
