Determination of particle density by sedimentation methods - Isopycnic interpolation approach1 Scope This document specifies a method for the determination of the density of solid particles or liquid droplets (below referred to generically as particles) dispersed in a liquid. The method is based on the fact that a particle wholly immersed in fluid experiences buoyancy equal to the weight of the fluid displaced by this particle (Archimedean principle), and if its mass force matches the buoyant force, it stops gravitational or centrifugal
