Influence of cell length on retrieval of particle size-distribution based on light scattering

•The cell length would influence the accuracy of particle sizing.•The measurement of scattered light distribution of particles will be amplified and transmitted to the particle sizing result.•In future, the influence of the cell length on the particle sizing must be considered.

In this paper, a study about the retrieval accuracy of particle size-distribution based on scattered light distribution is reported. A view is proposed that the ratio (L/RL/R) of the sample cell length   (LL) to the cell—detectors distance   (RR) affects the retrieval accuracy. The numeric simulation indicates that the larger the L/RL/R, the larger the retrieval error. Therefore, in future related measurement and studies, the ratio of L/RL/R must be taken into account.
