The H.E.L. Limited Subsieve AutoSizer (SAS) is a new addition to the established field of air-permeability particle sizing. It has been developed as a direct and improved successor to the widely used Fisher Model 95 Sub-Sieve Sizer (FSSS). The SAS adds automated functions, and electronically recorded and presented data, to an established particle sizing technique. The SAS uses the principle of pressure drop across a packed bed of powder. By varying the sample height, and hence the “porosity” of the bed, average surface area and particle size can be determined as a function of pressure drop in accordance with the Carmen equation. The SAS measures particle size in the range of 0.2 µm to 75 µm and has a compression accuracy of less than 0.05 mm.

Why Air-permeability Particle Sizing?
Air-permeability techniques generate average Specific Surface Area (SSA) data for a sample of powder. The SSA of particles has a significant impact on the physical properties of powders and has been the focus of much attention from such diverse communities as the pharmaceutical, paint, toner and geologic professions. The SAS has particular applicability to the Pharmaceutical Quality Control field where the quick and reproducible SAS-derived Surface Areas can be used to control batch-to-batch variation in important properties such as bioavail-ability and drug delivery.
