Laser Diffraction System Breaks New Ground in Dry Powder Particle Sizing

Equipped with the Aero S dry dispersion unit, the new Mastersizer 3000 from Malvern Instruments is extending the boundaries of dry powder particle sizing. Recent studies have revealed this new laser diffraction system will deal equally efficiently with a variety of materials ranging from pigments to milk powder and coffee, and delivers effective dispersion without particle damage, even for fragile materials. The modular design of the Aero S dry dispersion unit provides options for controlling dispersion that include an adjustable hopper, different feed tray designs and a choice of two different venturis — one that uses shear forces to disperse the sample and another that uses impaction. The flexibility of the system allows the user to develop a robust method for every type of sample and, compared with other laser diffraction systems, the Mastersizer 3000 significantly broadens the range of materials and applications to which this measurement technique can be applied.
