text: For polymers and polymer complexes that are monodisperse () as determined by static light scattering, a Zimm plot is a conventional means of deriving the parameters such as R, molecular mass M and the second virial coefficient A.
  One must note that if the material constant K is not implemented, a Zimm plot will only yield R. Hence implementing K will yield the following equation:
  The analysis performed with the Zimm plot uses a double-extrapolation to zero concentration and zero scattering angle resulting in a characteristic rhomboid plot. As the angular information is available, it is also possible to obtain the radius of gyration (R). Experiments are performed at several angles, which satisfy the condition  and at least 4 concentrations. Performing a Zimm analysis on a single concentration is known as a partial Zimm analysis and is only valid for dilute solutions of strong point scatterers. The partial Zimm however, does not yield the second virial coefficient, due to the absence of the variable concentration of the sample. More specifically, the value of the second virial coefficient is either assumed to equal zero or is inputted as a known value in order to perform the partial Zimm analysis.
