Particle Sizing with Dry Dispersion Can Be the Best Choice for Pharmaceutical Analysis
This paper looks at laser diffraction technology which when initially conceived only measured particle size by diluting a sample with a suitable diluent and pumped the mix through a sample measuring cell. It explains how the move away from using solvents encouraged the use of measuring sample dry ra...
How to Perform a Standardized Tapped Density Test for Pharmaceutical Powders
Tapped density is a significant parameter to explore the compressibility and flowability of pharmaceutical powders, which is useful to promote the approach of Quality by Design (QbD) and good manufacturing practices (GMPs). Standardization of apparatus and procedure is vital to get meaningful repeat...
Combining Laser Diffraction with Dynamic Image Analysis to Improve the Characterization of Abrasives
Size is not enough to ensure the consistency of abrasives and it is well known within the abrasives industry that the shape of the particles is equally as significant a parameter to control. The Bettersizer S3 Plus has proven to be able to characterize the size and shape of the abrasives simultaneou...
