✦ Synopsis

The resolving ability of the SIPP program operating on the regularization principle was studied in computer experiments and in real experiments on a mixture of particles of two different dimensions as well as on tobacco mosaic virus. I t has been shown that the limit of resolution in real dynamic light scattering experiments is achieved when the ratio of the characteristic times of the components is 1 : 2, provided that the contribution of the "slow" component to scattering is about twice that of the "fast" component.

Some practical rules that serve to obtain the best resolution of the two components have been formulated.
