Characterizing colloidal balance and dispersion.
How Does DLS Perform?
Mild Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light-weight, along with the scattered gentle intensity fluctuates as a result of Brownian movement.
Investigation:
The depth fluctuations are analyzed to estimate the hydrodynamic diameter with the particles utilizing the Stokes-Einstein equation.
Final results:
Supplies info on particle measurement, measurement distribution, and at times aggregation point out.
