What exactly is DLS?
DLS, or Dynamic Gentle Scattering, is a method utilized to evaluate the dimensions of particles suspended in a liquid by analyzing the scattering of light. It is especially helpful for nanoparticles, with sizes ranging from a handful of nanometers to many micrometers.
Critical Purposes:
Figuring out particle measurement and sizing distribution.
Measuring molecular excess weight and surface charge.
Characterizing colloidal balance and dispersion.
How Does DLS Function?
Light Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light, and also the scattered mild intensity fluctuates due to Brownian motion.
Evaluation:
The intensity fluctuations are analyzed to determine the hydrodynamic diameter from the particles using the Stokes-Einstein equation.
Effects:
Supplies knowledge on particle measurement, sizing distribution, and in some cases aggregation state.
