How can DLS Operate?
Gentle Scattering:
A laser beam is directed at a particle suspension.
Particles scatter mild, as well as the scattered gentle intensity fluctuates because of Brownian motion.
Evaluation:
The intensity fluctuations are analyzed to determine the hydrodynamic diameter in the particles using the Stokes-Einstein equation.
Results:
Provides information on particle dimensions, size distribution, and occasionally aggregation condition.
