In this paper we study the possibility of analyzing solutions of mixtures of spherical and cylindrical macromolecules, impinging on them with laser light and measuring the normalized second-order factorial moment, n(2)(T), of the scattered light. With this method we intend to determine the quotient of concentrations of the two solute fractions or the molecular weight of one of the components. The errors in these measurements are studied by means of a computer simulation method. The validity of the simulation method is experimentally proved with a mixture of two kinds of spherical particles of different size.
