What's DLS?
DLS, or Dynamic Gentle Scattering, is a technique utilized to measure the size of particles suspended in the liquid by examining the scattering of sunshine. It is very powerful for nanoparticles, with dimensions starting from a couple of nanometers to several micrometers.
Important Applications:
Analyzing particle sizing and dimension distribution.
Measuring molecular excess weight and surface area charge.
Characterizing colloidal security and dispersion.
How can DLS Operate?
Light-weight Scattering:
A laser beam is directed in a particle suspension.
Particles scatter gentle, along with the scattered gentle intensity fluctuates as a result of Brownian movement.
Investigation:
The depth fluctuations are analyzed to estimate the hydrodynamic diameter of the particles utilizing the Stokes-Einstein equation.
Final results:
Gives information on particle size, size distribution, and occasionally aggregation point out.
