Exactly what is DLS?
DLS, or Dynamic Light Scattering, is a method utilized to evaluate the scale of particles suspended in the liquid by examining the scattering of sunshine. It is very efficient for nanoparticles, with sizes ranging from a few nanometers to numerous micrometers.
Crucial Apps:
Pinpointing particle sizing and size distribution.
Measuring molecular excess weight and surface charge.
Characterizing colloidal stability and dispersion.
So how exactly does DLS Work?
Light Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light-weight, and the scattered light depth fluctuates as a result of Brownian motion.
Analysis:
The depth fluctuations are analyzed to work out the hydrodynamic diameter of your particles utilizing the Stokes-Einstein equation.
Results:
Provides details on particle dimensions, sizing distribution, and at times aggregation condition.
