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. gyms new albany indianaWebJun 11, 2015 · In dynamic light scattering (DLS) we are usually mostly concerned with the level of intensity fluctuations – nevertheless we do need to see a good signal before we can analyze it. The signal strength is the scattering intensity and it is measured in photons per second, or most often as in the Zetasizer in kilo counts per second, kcps for short. gyms new albany in

"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.
