NettetThe intensity-weighted distribution is specific to the dynamic light scattering (DLS) technique. In that case, the results are expressed as a measure of the intensity fluctuations of the light scattered by the particle. maplestory miracle cubeNettet28. aug. 2024 · Particle size distributions were expressed on both light scattering intensity and particle volume basis. Both instruments operate in the backscattering mode. A standard quartz cuvette of 10-mm path length was used for both DLS instruments. All the measurements were performed at 25 °C ± 0.1 °C. maplestory milkNettetdistribution and corresponding intensity weighted distribution showing the meaning of the Z-average.
