Characterizing colloidal balance and dispersion.
How Does DLS Function?
Light Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light-weight, along with the scattered mild intensity fluctuates because of Brownian movement.
Examination:
The depth fluctuations are analyzed to compute the hydrodynamic diameter on the particles utilizing the Stokes-Einstein equation.
Outcomes:
Offers information on particle size, size distribution, and at times aggregation state.
