What on earth is DLS?
DLS, or Dynamic Light-weight Scattering, is a method used to measure the scale of particles suspended in the liquid by analyzing the scattering of light. It is particularly effective for nanoparticles, with measurements ranging from a number of nanometers to many micrometers.
Critical Purposes:
Identifying particle dimensions and size distribution.
Measuring molecular excess weight and surface charge.
Characterizing colloidal steadiness and dispersion.
So how exactly does DLS Do the job?
Light-weight Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light-weight, as well as scattered light-weight depth fluctuates on account of Brownian motion.
Evaluation:
The depth fluctuations are analyzed to work out the hydrodynamic diameter from the particles utilizing the Stokes-Einstein equation.
Final results:
Gives info on particle size, sizing distribution, and in some cases aggregation point out.
