Measuring molecular bodyweight and surface demand.
Characterizing colloidal steadiness and dispersion.
So how exactly does DLS Work?
Light Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light, along with the scattered light depth fluctuates because of Brownian motion.
Analysis:
The intensity fluctuations are analyzed to determine the hydrodynamic diameter from the particles utilizing the Stokes-Einstein equation.
Success:
Delivers facts on particle dimensions, measurement distribution, and at times aggregation condition.
