Low-angle laser light scattering (LALLS) is a technique used primarily to characterize the size and distribution of particles, molecules, or macromolecular substances in a solution or suspension. LALLS measures the intensity of light scattered by particles when illuminated by a laser beam at low scattering angles, typically less than 5 degrees from the incident beam direction.
