Measuring molecular body weight and surface charge.
Characterizing colloidal steadiness and dispersion.
So how exactly does DLS Operate?
Gentle Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light, and the scattered mild intensity fluctuates resulting from Brownian motion.
Assessment:
The depth fluctuations are analyzed to compute the hydrodynamic diameter on the particles using the Stokes-Einstein equation.
Results:
Provides details on particle size, sizing distribution, and occasionally aggregation point out.
