What on earth is DLS?
DLS, or Dynamic Mild Scattering, is a way utilized to evaluate the size of particles suspended in the liquid by examining the scattering of sunshine. It is especially powerful for nanoparticles, with measurements starting from some nanometers to quite a few micrometers.
Critical Purposes:
Analyzing particle sizing and sizing distribution.
Measuring molecular weight and surface charge.
Characterizing colloidal steadiness and dispersion.
So how exactly does DLS Operate?
Mild Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light-weight, as well as scattered light-weight intensity fluctuates as a result of Brownian movement.
Investigation:
The depth fluctuations are analyzed to calculate the hydrodynamic diameter from the particles using the Stokes-Einstein equation.
Outcomes:
Offers information on particle sizing, sizing distribution, and from time to time aggregation condition.
