Quantitative particle size distribution analysis by Laser Diffraction and Differential Centrifugal Sedimentation
Both Laser Diffraction (LD) and Differential Centrifugal Sedimentation (DCS) are used for quantitative particle size distribution analysis of samples in the sub micron region. LD can be described as a low resolution, wide dynamic range technique which is robust, fast and easy to operate. DCS, is a high resolution particle sizing technique, and is now similarly robust, fast and simple to use. Historically however, DCS has been limited in dynamic range; but with the introduction of speed ramping, the dynamic range capabilities of DCS are now much improved.
