What Are the Methods to Measure Sedimentation in Catalysis?
Several techniques are used to measure sedimentation in catalytic systems:
1. Sedimentation Balance: Measures the settling rate of particles in a fluid. 2. Ultracentrifugation: Uses high centrifugal forces to accelerate sedimentation, allowing for the determination of particle size and density. 3. Dynamic Light Scattering (DLS): Measures the fluctuation in light scattering due to particle movement, providing information on particle size distribution. 4. Optical and Electron Microscopy: Visualizes the settling behavior and morphology of catalyst particles.
