What exactly is DLS?
DLS, or Dynamic Light Scattering, is a way accustomed to measure the scale of particles suspended inside a liquid by examining the scattering of light. It is especially effective for nanoparticles, with sizes ranging from a few nanometers to various micrometers.
Critical Applications:
Figuring out particle dimension and dimensions distribution.
Measuring molecular weight and floor cost.
Characterizing colloidal security and dispersion.
How can DLS Get the job done?
Light-weight Scattering:
A laser beam is directed at a particle suspension.
Particles scatter light, and the scattered light-weight intensity fluctuates resulting from Brownian movement.
Investigation:
The depth fluctuations are analyzed to estimate the hydrodynamic diameter of the particles using the Stokes-Einstein equation.
Final results:
Gives info on particle dimension, dimensions distribution, and often aggregation condition.
