Destabilization Characterization

Dispersions instability often results from two different physical processes :

particle size increase due to coalescence or flocculation (droplets or aggregates);

particle migration within the samples giving rise to creaming or sedimentation.

The TurbiScan MA 2000 performs a kinetic analysis to detect these phenomena at an early stage.

Stability No particle size or volume fraction changes occur.  BS & T remain constant and all time scans superimpose).

Particle size variation Particle size variations (flocculation or coalescence) induce l * or l changes, and therefore BS & T vary with the height of the sample.

Particle migration Particle migration phenomena (creaming or sedimentation) induces particle volume fraction changes at the extremities of the sample. The TurbiScan Ma 2000 calculates the migration rate by following the migration front.
