Nettet19. sep. 2024 · Discussion was done on how the Z-average, the three types of size distribution (i.e., intensity-weighted distribution, volume-weighted distribution, and number-weighted distribution), and the PDI value are calculated from DLS measurement. Understanding the origin of the DLS data is important in order to avoid misinterpretation.
