What is hydrodynamic analysis?

Hydrodynamic analysis with a stability analyzer explains the moving of suspended substances within the measurement period regarding the forming of separated phase and migration rate, which is beneficial to the understanding of destabilization processes, behavior predicting, and formulation development. In most cases, hydrodynamics can be studied when sedimentation, creaming, or breaking occurs. The following figure illustrates typical spectra of sedimentation. With the help of the analysis software, the range of the characteristic peak to be analyzed can be manually limited and the change curve of phase thickness over time will be automatically generated. By limiting the starting point and the ending point of the change curve, migration rate can be obtained. Besides, mean particle size calculation based on the gravitational liquid sedimentation method can be realized.
