Abstract: The invention concerns a method and system for determining dissolution properties of a particle. The method comprises providing into a vessel dissolution medium capable of dissolving the particle and providing the particle into said vessel in contact with the dissolution medium for dissolving the particle. According to the invention, the particle is trapped in a particle trapping zone formed at a predetermined location in the vessel, the particle trapping zone being formed preferably at least partially by continuous hydrodynamic motion of the dissolution medium. Residue of the particle is imaged while being trapped in said particle trapping zone for providing a plurality of sequential images of the particle residue. Finally, at least one dissolution property of the particle is determined based on the sequential images.
