Centrifugal sedimention methods

Centrifugal Sedimentation Methods These methods extend sedimentation methods into the submicron size range. Sizes are calculated from a modified version of Stokes equation ... 

The second activity is characterized by the revitalization of older instrumental methods such as gravitational and centrifugal sedimentation methods. Redesign, modernization with advanced electronics, and user-friendly, computer-aided analysis have extended the instrument product life cycle. A good example is disc centrifuge photosedimentometry (DCP), the subject of three chapters in this volume.

Some advantages of disc centrifuge sedimentation method include (1) the disc centrifuge allows a wide dynamic range of particle size analysis, depending on particle density, from 30 jun down to 0.01 pm (2) any particle which can be centrifuged can be analysed (3) large representative sample (lO particles) (4) requires only 0.5-1.0 ml sample of 0.05-0.5% concentration.
