The problem of space coincidence of aerosol particles in the sampling volume of laser time-of-flight particle analyzer has been studied. Using model distributions, it is shown that particle coincidence in space may lead to errors in determining aerosol disperse composition and concentration. The retrieval of parameters of the initial aerosol is shown to be ambiguous when the inverse problem is solved. Possibilities of improving measurement accuracy and stability are discussed.
