Abstract
A system for emitting and detecting electromagnetic radiation of multiple wavelengths to observe the motion of particles in a polydisperse solution in order to size the particles is provided. The system includes a first and second light sources constructed to emit a first and second beams of electromagnetic radiation at substantially a first and second wavelength, respectively. The beams are directed to a specimen chamber such that a portion of the beams scatter when illuminating the particles, and wherein the scattered portion of the beams are directed to a sensor. The first and second wavelengths are different from each other and a recorder is connected to the sensor. At processor controls the light sources in a time-division fashion, and from the resulting images the size of particles can be determined by tracking the motion of the particles.
