Characterizing colloidal steadiness and dispersion.
How Does DLS Function?
Gentle Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light, as well as scattered light-weight depth fluctuates as a consequence of Brownian motion.
Analysis:
The depth fluctuations are analyzed to work out the hydrodynamic diameter with the particles utilizing the Stokes-Einstein equation.
Effects:
Supplies info on particle dimension, dimension distribution, and occasionally aggregation condition.
