Why use Dynamic Light Scattering (DLS)?
DLS has several advantages over other laser light scattering technologies available today. First, it is an absolute measurement, where knowledge of the composition of the suspended particles is not needed. This can be helpful if the optical properties of the suspended particles are not known or if the suspension is made up of particles with different optical properties. Second, DLS can size particles down to 1 nm, which is ideal for making measurements on proteins or other types of nanoparticles. Laser Diffraction methods can reliably size particles down to 100 nm or less.
