A dynamic light scattering (DLS) experimental system has been set up to study the influence of the sampling rate on the precision of monodispersed particle sizing. Several different parameters relating to the measurement, such as the sampling rate, the number of the correlation channels, the storage depth, and the lag time, are selected to execute the DLS measurement. The experimental results obtained in different cases are reported, and the influences of the sampling rate on particle sizing are also discussed. From the results and discussion it can be seen that the sampling rate plays an important role in the measurement of the particle size. The variety of the sampling rate can lead to the presentation of different correlation functions and then different precision levels for the particle size. In conclusion, a suitable sampling rate is presented to direct the measurement of test particle size.
