Particulate Systems, a brand of Micromeritics Instrument Corp., has been granted exclusive global distribution of the H.E.L. Limited Subsieve AutoSizer (SAS), a modernized and improved version of the Fisher Model 95 Sub-Sieve Sizer. The SAS has improved the established air-permeability particle sizing technique. The instrument combines the benefits of true unattended operation, ease of use, touch-screen control, and data capture using H.E.L.’s proprietary WinISO software platform. Air-permeability techniques generate average specific surface area data for powder samples. The specific surface area of particles has an impact on the physical properties of powders and has been the focus of much attention from pharmaceutical, paint, toner, and geological industries. The SAS has particular applicability to pharmaceutical quality control where quick and reproducible SAS specific surface area analyses can be used to control batch-to-batch variation in important properties such as bioavailability and drug delivery.
