Characterizing colloidal balance and dispersion.
How Does DLS Work?
Light Scattering:
A laser beam is directed at a particle suspension.
Particles scatter mild, and the scattered light intensity fluctuates on account of Brownian motion.
Assessment:
The depth fluctuations are analyzed to estimate the hydrodynamic diameter with the particles using the Stokes-Einstein equation.
Outcomes:
Provides info on particle dimension, size distribution, and in some cases aggregation point out.
