WebJan 24, 2024 · Basic set-up for a DLS experiment. To avoid saturating the detector, the light from the laser is attenuated before entering the sample cell. A detector is placed at a fixed angle to collect the light that scatters at that angle. The resulting intensity of scattered light is measure as a function of time. WebSo, by DLS one has determined the intensity weighted diffusion coefficient. The diffusion coefficient is inversely proportional to size. Therefore, the “Z-average size” is the intensity weighted harmonic mean size. Concluding Comments Despite the convoluted meaning, the Z-average size increases as the particle size increases.
