A key feature of the new Morphologi G3 automated particle characterization system from Malvern Instruments is a fully integrated Sample Dispersion UnitMorphologi G3 provides microscope quality images and delivers statistically significant data through the rapid analysis of hundreds of thousands of particles, with little or no user intervention, giving information on both particle size and shape. The software-controlled dry powder dispersion system reduces sample preparation times, significantly improves repeatability of measurements and offers safer handling of hazardous substances.
Reliable particle characterization of dry powders requires strict control of dispersion conditions. Using the Morphologi G3, sample is dispersed with an instantaneous pulse of compressed air. Precise control of dispersion pressure, injection time and settling time ensures highly reproducible measurements across a broad range of samples.
Measurements are made in an enclosed sample carrier, minimizing environmental exposure and ensuring safer material handling, especially when measuring pharmaceutical actives or toxic materials. Multiple aliquots can be prepared in advance, ready to use at the next measurement.
