Dispersion of Nanomaterials in Aqueous Media: Towards

Disc Centrifugation is a separation technique used to determine particle size distribution using centrifugal sedimentation in a liquid medium. The particles sediment within an optically clear and rotating disc and the amount of light scattered by the particles when they reach the edge of the disc is recorded and converted into particle size distribution using Stokes' law.

BI

The BI-DCP is a centrifugal particle size analyzer that uses monochrome light to detect the sedimentation of particles. Advantage of a centrifuge over other types of particle analyzers is the fact that absolute measurements (according to Stokes'' law) are performed and no assumptions in the interpretation of measurement values have to be made, that would introduce uncertainties.

Basic Theory of Particle Size Analysis by Sedimentation

Sedimentation can be either gravitational (1 g-force), or centrifugal (many g-force). Gravitational sedimentation is normally limited to particles of relatively large size, because the rate of sedimentation for small particles is too low to give a practical analysis time, and because Get price
