Groups working with nanoparticles often have a special focus on the smaller size range. For this research, it is then very appealing (and tempting) to universally prefer the number distribution. This is because number distributions will generally report the smallest size measured. While this may be OK with good data, … See more “We have several data sets with low PDI (<0.1), single exponential decay, low cumulant fit error(~10^(-4)). The intensity-distribution size and the cumulant fit size are similar. But the number-distribution size (d=33 nm)and … See more In some cases, peaks may get “lost” or disappear in the transformation. For example, in the graph below, a protein sample showed an … See more WebUsing Mie theory, the transform of the DLS intensity distribution to other types of distributions is straightforward. The intensity distribution gives us the amount of light scattered by particles in the diameter range of x to x+Dx, while the Mie scattering formula tells us how much a particle of a certain diameter scatters. how to open emojis in vs code
